Edit: to be fair... Out of all the riddles this was the simplest
Plot twist: Cassandra doesn't care that she didn't get to be queen because she's so lucky that she ends up walking into Paul Rudd whenever she goes anywhere.
She should play lottery.

@@zoe1701 Percy Jackson isn't canon to the Greek mythology.

After this riddle, Cassandra lives a luxurious, yet depressing life with no meaning as she won 13 lottery tickets in a row, met a perfect husband that she doesn't know if she loves her for who she is or money and has perfect children that stop visiting after she destroyed them in every game they played when they were young(can not lose even when she wanted)

This is a theory that Cassandra is not faking.
At 2:43, you can see Cassandra changing her smile in a seemingly anticipated way when the narrator says "That's theoretically possible". This indicates that she knows how absurd the odds are, and is hoping that they might believe her. And we know that Cassandra can hear the narrator speaking, because, at 4:39, unlike the rest, Draco is doing a facepalm, indicating that he knew he was close, and the only thing he needed to do was to be good at math.
Also, at 3:43, she seems genuinely sad. Like in a "Nobody believes me!" sad.
But the biggest piece of evidence is in Greek mythology. Cassandra is a prophet who was blessed by Apollo when Cassandra was in a relationship with him. When Cassandra decided to break up with Apollo, he cursed Cassandra to speak true prophecies, but nobody believes her. And as the saying goes, history repeats itself, so coincidence, I THINK NOT!

If Cassandra did, in fact, play fair, she would be the unluckiest luckiest person ever. Imagine you win fair and square in a 1/13 nonillion chance just to be disqualified because someone isn't sure whether you cheated or not.
Marko Gjakovski that isn’t completely true. There are more permutations to achieve a sum of that but only one such set of numbers that add to be 700. Therefore, 385 is more common
*IF* Cassandra was TRUE,
*THEN* she was :
- Good at *Arithmetic* (Addition)
- *Lucky* (To get Least Possible Number)
- Honest
But, again *UNLUCKIEST LUCKY*
@@mihir1181 oh god, it ACTUALLY DOES
If she did get a score of 700 she was damned either way. Either she tells the truth and no one believes her, or she lies and gives a lower score (in which case she's dishonest).
The smart thing to do would have been to make up some score that was possible (i.e. a multiple of 5 between 100 and 700) that is greater than 400 (the expected value, and therefore being deemed lucky), but not so high that it would have

As a programmer, I thought "I'll just simulate this instead of thinking about it logically"
On my first run of 20 rolls, I got 385 as a result, and I was pretty sure I knew the answer from then.
The way you could have solved this in like 3 minutes but bro was really like "no no no, let me think about this"
Programming moment
As a low level stats student i use z distribution to approximate and find that 435 is the highest score that gives more than 10% p-value. 470 for example is less than 1%
@@bluejay9638why spend 5 mins on a task when you can spend 30 mins writing a program that will do the task for you
I'd like to add that Alexa revealing her TRUE SCORE, no matter how low it was comparatively, shows great honesty. She could've easily brought it up a few digits in the hope of beating her siblings for the highest score, but she was honest with the value she earned, even when it was the lowest of all.
Either that or she intentionally picked a low multiple of 5 knowing 3 of her siblings would try to cheat.
Or maybe she got an absolutely horrible score and bumped it up
The highest score you can get away with is 435. So if by luck you got 450 you should lower this. I calculate using z-score approximations
Cassandra stans be like: "1 in 13 nonillion is still possible."
Lmao
Cause I mean yeah, it is. Humans seem to think improbable is impossible.
It's possible but the feasibility is what really matters.
If you win a lottery thrice in a row in a week, everyone will likely believe that you did something behind the scenes
@@DeathnoteBB Just because it's possible doesn't mean you will get jt it's like guessing a number i'm thinking between 1- 1 trillion Sure it's possible but the chances of guessing correctly is so unlikely that it may as well be impossible
@@fora1924 But my point is if it ever happens, that was always a possibility.
Cassandra's score is still more likely than finding Paul Rudd in Mali, and then finding him again in Brazil five seconds later.
As of right now that’s impossible since you can’t travel from anywhere on Africa to anywhere on South America in 5 seconds.

@Shen, teleporter comin right up!
Pera Kojot the problem is that we have to carry around our mass...
Remember! The rules wasn't just about luck, it was about logic too. Even IF Cassandra played fair and got 700, she would have OBVIOUSLY known that it is an unbelievable number, and faked it to a lower one. The only real rule was to get a number that is the highest multiple of 5 that stays within the general bell curve of the probabilities of the total score. Picking 495 would get you an easy win. Even picking 425 instead of 423 would've won.
hey, you're right!
@Sohanur Rahaman the thing is you need to be 90% sure they cheated, if it’s below that and is a reasonable answer then even without honesty you can win.
@Sohanur Rahaman yes
No, the real thing to do is halfway through your rolls exit and say "hey, I keep getting 35, I think there's something wrong with the dice!"
I used z-distribution to approximate though, the probability of getting 700 or more is around 1/trillion squared. You haved better chances of winning the megalotterly 3 times in a row. Anything above 470 would have less than 1% chances. best chance to win would be to fabricate 435 based on z score
Honestly, it's not the worst method of selecting a heir.
It picked out three people who for various reasons, shouldn't be rulers.
Wrong. Cassandra for life. She got 700. She should go to war if Alexa don't abdicate. Cassandra was higher.
@@divergentlife493 I can tell you are a glupi idiota
@@divergentlife493 Even if she did legitimately get 700, it's still unlucky that she got a high enough score to be suspected of cheating. So eliminating her was still valid.
@@divergentlife493she should have realized that it’s not believable.
@@divergentlife493 did you know the probability for flipping a coin and getting heads is 50%? And did you know the probability for flipping 100 coins and getting heads 100 times is also 50%?

As punishment for cheating, Cassandra was sentenced to execution by firing squad. But all the guns kept jamming.
HAHAHAH

Funne Ace Attorney
Hahahaha
Cassandra went on to become the heir due to her luck in every single execution attempt and early life.
Imagine being Cassandra: You actually get 700 with absolutely insane luck then get disqualified for being too lucky which is literally what the king is looking for in an heir
But he looked for honesty above all, and since the probability of Cassandra not being honest was very high, it’s understandable why she was disqualified
Also if she was disqualified, she’s not the luckiest. Alexa is.
Only way to get 700 is 35 on every roll, which have 1/36 probability per roll. (1/36)^20 about 1/100 trillion squared. Better chances of winning mega jackpot 4 times in a row and getting struck by lightning in one month than that. But i'd put 700 just to troll them
@@dragorn3212it's still not impossible
@@BigHH88
the rules never said that they only get disqualified if it was impossible, it only said that they'd be disqualified if you can reasonably say that you're 90% sure they cheated
Eliminating Cassandra is still fair according to the rules of the King, since he said you had to be above 90% sure, and Cassandra’s result was extraordinarily unlikely. So even if she was honest and got 700 she still fairly lost because the kings rules were that you had to more than 90% sure
Not to mention that getting disqualified simply because no one could be sure whether she was honest would make her unlucky anyway!
Imagine the advisors just going: “ Too high, too improbable, not a multiple of 5, and your the only one left standing.”
Hopefully, they'd know to say "you're" and not "your."

If only Draco had decided to be memetic and go with 420, he would've gotten away with it.
After the event, Cassandra goes to a cassino, win everything. Then buys a lottery ticket, that she also wins. She may be not the Queen but she owns most of the kingdoms net worth 👍🏻
Good ending
with the luck she had, I think she would be extremely unlucky for the rest of her life.
Cassandra then went on to get the wr on Minecraft. possibly.
And then Casandra beat every speedrun possible with the best rng ever.
After that, the king begs for all of her riches, and even says she could be the queen if he had all of the money. Cassandra agrees, making her the queen.

I struggled deciding between A and C, specifically because being lucky was considered important, but the whole statement of 90% sure kind of dictates that incredibly good scores are no good.
to good to be true is the phrase, plausible but utterly improbable
the 90% means that from random chance there's still a 30% chance probability that someone gets disqualified even if everyone plays fair. The best strategy would be to play the number 435 no matter what

If Cassandra did honestly score 700, she would not just be lucky, she would transcend the metaphysical principle of possibility. She could beat an omniscient, omnipotent being at a game of poker with royal flushes with every hand; she would be born with a genetic mutation that makes her immortal; she could deflect a comet hitting the Earth with a feather; she would not only be a queen but an empress of humanity itself, billions worshipping her as a goddess for all eternity.
What's more likely: Cassandra's rolls or tripping and falling through a foot of stone floor by having all your atoms sync up with the atoms in the floor and phase through? (btw due to quantum physics both are technically possible lol)
Cassandra's roll
The atoms one is basically impossible because atoms never touch they push back. Even if your atoms align they will push back and stop you from falling through.
what's more likely: cassandra rolling 700 700 times or the universe randomly collapsing (both are possible)

@@baguettegott3409 wait what is this referring to
@@icewing202 this guy called dream, a very popular Minecraft UA-camr, had a bit of a controversy a while ago where he was accused of cheating at speedrunning Minecraft. The issue was, like with Cassandra in this video, that he was being wayyyy too lucky to be mathematically plausible. So some people wrote a big maths paper to accuse him.
And he, in turn, hired an anonymous astrophysicist to mathematically prove his innocence.
He was not innocent though. The maths was pretty clear, despite the astrophysicist, and eventually he also admitted to cheating I think. (He lied and said it was somehow an accident or something, but he did admit that the speedruns weren't legit)
Fact: Even if you picked Paul Rudd a 3rd time, that's still about 30 times more likely than getting a score of 700.
What’s the math tho. Just curious
7,500,000,000^3 = 421,000,000,000,000,000,000,000,000,000 which is 30 times less than 13 nonillion.

The heir was supposed to be picked based on arithmetic, luck, and honesty. We know Alexa isn't lucky and might not be good at math. But she is honest. Cassandra is good at arithmetic and the odds are she is luckier than Alexa. But probably not honest.
The only way Alexa wins is if honesty was the only factor.
@@falkorornothing261 She wins because of the 90% rule.
The real winner is the advisor. Only someone with outstanding arithmetic can figure out that 3/4 of them cheated, and that the only one that likely didn’t cheat got the average score.
Plus, he was very honest, not lying about the math to pick someone he wanted to win.
Imagine getting disqualified because you’re just bad at maths

@Burning Rubbish Sure is, the advisor found Paul Rudd
I have a feeling that it was the king who was lying. This test is meant to pick out the most able advisor, not heir.
The best number to pick in my opinion is 630 as this is 90% of 700 and therefore the highest number you can have and be within the 90% confidence interval. The adjudicator may disbelieve you (as I would) but he isn’t allowed to disqualify you according to the rules.
But the 90% confidence is based off advisors personal opinion
The second riddle that i was able to solve. It feels so good. I love your riddles, they are so good
Imagine Draco's result was 425 but he wrote it wrong and so he lost the throne .
But they have to be good in arithmetics.
@@Hewhoroamstheinternet Huh, that's true!
he should've had 420 man
@@anishmitra8567 It didn't say they have to be the closest to average, but they had to be believable. Even 500 would be within a 90% probability.
Imagine, Cassandra did in fact play fair but you thought she was lying, she goes on to get orphaned and adopted by another royal family and rolls the exact same and that royal family also thinks she is lying then orphaned again but adopted by a normal family, she goes on to get struck by lightning and gets superpowers then gets a lottery ticket and wins.
Wot?

Nadia N it was a very short one in the comments of this video, it’s the one we’re replying to.
This is the first (and only) TedEd riddle I’ve been able to solve!
I got this but for a different reason - I added up all the dice numbers for 120, times by the number of rolls for 2400 and divided by the number of sides on a side for the likelihood each side would show - 400, and 385 is the closest to this average
My favourite part of this riddle is Paul Rudd.
Bertram achieving 840 is like that one time as a kid I was playing a card game and announced that I had "5 aces" before promptly being called out for it, LOL
I mean, if its one of those decks you find at a school that are really screwed up then...
That depends if it is a game played with more than one deck or not.
First time I played liers dice, I said that I had 72.
To be fair, I was quite drunk.
Imagine the lottery never cashing out because the winner is always too lucky.
Meanwhile, poor Casandra who got picked by the god of luck to be queen and is genuinely amazed at her own luck is feeling cheated in the corner.
Even if Cassandra did really get 700 and then got disqualified because the advisor felt she was cheating then that makes her unlucky and so she doesn't meet the criteria to be the next ruler.
thats ingenius man
Not really, the adviser didn’t decide wether to disqualify Cassandra by flipping a coin, he used logic. Anybody else would have been disqualified, not just Cassandra.
You know, all this heir selection does is pick either the most honest candidate, or the one who's best at lying, and it's way more skewed toward those better at lying. Bertram made an unbelievable lie, Draco made a more believable but still impossible lie, Cassandra either told the truth and was really lucky or didn't quite lie well enough, and Alexa either told the truth and was slightly unlucky or was the best liar of the heirs. Considering how many of the others did or probably did lie, Alexa lying and picking a smaller, reasonable, and more probable number would actually make her way more likely to become queen if she had any idea that the others would lie.
Ummm. Yes
"All hail Queen Alexa"
"My queen, play despacito"
Yup, Alexa and Cassadra are only ones that could be telling truth as both have numbers within the realm of possibility. But there is no sure way that we would know that either of them is lying so we would go with the most likely odds, even though luck could have given Cassandra the edge on hitting the highest score or giving Alexa the odds on hitting a reasonable score. Or the way their luck is seen is that the luck will get the person to win rather than just a highscore. Either way this really could go two ways, just one more likely than another.
Or they could just actually roll their dice. Alexa would have no real reason to spend time making up a reasonable number when she could generate a legitimately reasonable number in a few minutes. With the premise that she would know the others would lie, it would actually be very detrimental to lie.
Alexa would still be the best candidate as she is both least likely to lie since she chose to fake a score below average and second because she either had the arithmetic to figure out the average score and that the answer must be a multiple of 5 OR she actually rolled the dice.
I'm actually really excited I got this right in actually pausing the video. Draco got me to actually consider the math.
Yo this video was awesome! Thank you

Plot twist: Cassandra was the luckiest human ever who would discover a cure-all drug for human-retated diseases by pure chance had she been made queen, so you just missed out big time.
But the very fact she rolled a 700 and was disqualified because of it means she wasn't the luckiest she was the least lucky so yeah she would of created the cure all drug and then accidentally spilled it all over her notes destroying them.
@@TheGreatDrake *would have
@Fernando the Boomer Knarmd Then by pure chance it was flammable and it got burned into ashes
That's also what happened to Cassandra in Greek myth who was curse with telling true prophecy but will be ignored by everyone.
Plot twist: the king was unluckier than Cassandra was lucky because he made the rule to find the luckiest child, but accidently disqualified his luckiest child instead for his least lucky child.
i really love the way of teaching this mathematical problem/stuff, All the education system should follow this style.
Supprisingly, this was easy!
Lucky: The child should roll the dice with the highest numbers 20x in a row
cauculate the highest score u can get for 1 roll and multiply it by 20
and honest will follow along
No one will believe Cassandra anyway. And Draco’s father will hear about this, obviously. 😂
Ah yes I was waiting for this comment
yeah, Draco's father is the king.
@@funtm7 Ummm... You don't get the reference.
HP reference ;
@@brazenRenascent, its cause he thinks it matches his eye color. ;D
The easier answer:
Step one: Check that you have green eyes
Step two: Ask the cheating children to leave
What?
I found the reference!
no talking about eye colors!!!!!!!!
@@iamhub2736 that's the way we do it here
@@rania9534 Let me fill you in on the in-joke here. One of the earlier featured riddles on this channel boiled down to: "There are 100 prisoners on an island and all have green eyes. Any one can ask to leave at any time; if they have green eyes, they will be freed, but if they do not, they will be executed. None of them know their own eye color, none of them can check their eye color or communicate with each other, and none of them are willing to risk leaving unless they know for certain their eyes are green. What one statement can you make to the 100 prisoners that results in their escape *without* giving them any new information?"
So the in-joke is to apply the "green eyes are a free ticket to leave" logic to every other riddle in some form or another.
Plot twist: Cassandra actually played fair and got lucky while Alexa just picked a random number that turned out to be the most reasonable
Dream bout to be suing Cassandra for plagiarism soon

@@shikhasinha736 _good luck i am hiding behind 500 more riddles_
this was one of the easiest puzzles
This one is actually easy 😃 unlike some of their older ones 🤩🔪
What's so fascinating about their riddles is that at first, it seems so complicated with many restrictions and requirements, but as the video progresses, the problem gets simplified more and more and more until a point you go: "God, it's so simple, why didn't think of that earlier?" That's what keeps you clicking on their riddles again and again, even though you know you won't get it right. That's the magic of riddles.

Dream Stans: *seems legit*
Meanwhile in a realistic scenario, the servant hears the results and chooses the one who will benefit him the most.
Is Cassandra named this way because nobody believes her score, in reference to Greek mythology? (I have understood that her name must begin by C of course ...)
You've cracked the code

The Izzet League
@@siegfried1422 yay another magic nerd
Dang right
Izzet True?
Cassandra should have raised her hand and told the royal advisor that something was wrong with her dice. If they were constantly ending up with the same number, they could be defective or weighed dice.
If the test was for luck, honesty, and being good at arithmetic, it could have been a secret test of character to see if she recognized her dice were loaded and if she would admit it.
Let the advisor know the dice are acting suspicious and try it again with working dice. That's what a smart and honest ruler would do.
There was a stipulation that all th edices were fair.
@@shloksinha2075 That's what they were told, but if I got the highest rolls on both dice more than 4 or 5 times in a row, I'd be getting suspicious.

@@bisqkuit1882 This was the reason why I looked for this video again Lmao
what does this mean?
@@Hyyacinth Basically at the end of last year Minecraft speed runner Dream was put under investigation for cheating and manually altering variables in a couple of his speed runs (specifically the ones that determine the odds of Piglins giving ender pearls in trade of gold and the chances of a blaze dropping one of its rods, both of which are necessary to beat the game). The speed runner admins said he altered the variables and cheated while Dream said that he just got lucky and both did research into their arguments. In the end they both decided to drop the debate and it’s basically become a meme in itself.
@@512theVagabond Ohhh okay, thanks for telling me :D Did he actually cheat tho?
