You are amazing and such a blessing to the students taking AP Stats tomorrow. The way you explain, the examples you use, and the emphasis on important topics- YOU are such a help. Cannot thank you enough,.
How come you were allowed to multiply (at 23:12), (.02*.95) and (.98*.15), when they aren't independent. Its 95% positive if there is a 2% change of heart burn, thats not independent? Please explain.
Ali Algabri it’s conditional probabilities. The 95% is on the condition that 2% chance of heart worm. If the second even is on the condition of the first you can multiple them without being independent. Probability of A and B = probability of A times the probability of B on the condition that A has occurred. This is true regardless of independence.
Ali Algabri hard to explain in words better if I could write it out. If you are trying to find the probably of A and B, if they are independent you can just multiple P(A)*P(B). If they are not independent or you don’t know them probability of A and B is P(A)*P(B|A)
My exam is today. My teacher is super sweet, but she kind of taught the course in an order to where my pattern recognition could not pick up on this sort of thing. It's finally starting to click. I really love stats (just not the class, lol). Wish me luck 0,^,0.
Love how the actual conditional probability problems are skipped over. How is the heart worm problem done? There is no explanation as to why it’s (.02 * .95) and not (.02 * .166)
It’s .02*.95 because they were trying to figure out the probability of heart worm and positive test result, so the two values were multiplied. The .166 is from both branches of the tree, (heart worm and positive)+(no heart worm and positive). Hope that helps :)
.166 is the chance of having a positive result, be it through the dog having heart work which is a .02 chance or through the dog not having heartworm which is .98. You take these two numbers and multiply them by their respective chance of the dog getting a positive result, for having heart worm it would be .02*.95=.019 and .98 *.15=.147, you would then add these two values to get .166 because the question asks what is the probability of the dog having a POSITIVE result no matter wether it has heartworm or not.
I thought it was moderately easy, but it takes pausing to think. I feel it takes some right and left brain. I think it would also generally be interesting for someone who likes the social sciences. Definitely watch the youtube videos though. You can pause when you need to, etc. In class, it took unnecessarily long to get through the topics, which makes it harder for some people, but school systems at least organize your learning schedule and content for you, so AP is better than a CLEP in my opinion (I just want to convey the AP class is definitely something to put the work into, even if it is hard). Supplementation like this video (and Charlie Lindleof's videos) is definitely good, even though I found it sort of easy to learn in class, personally. A lot of people around me did struggle. My great uncle has a law degree and an economics degree from Harvard from back when people could afford to do that, and he says it's because he audited the classes before taking them. Too pricey to do that now. UA-cam is like a free peek at the class, which is so useful to keep your gpa high and your understanding clear and full! ~~ An unusually long answer from an adult college student
@@mporinchak their teacher might teach it a bit different which might have confused him because my teacher he didn’t really do the equation for the table and he made a table that totaled 1000 which we call the hypothetical 1000 to get the probability
If there's any way I pass this AP test after falling asleep in class for the entire year, this is the way
Howd you do?
@@GaurPand They never returned....
@@ItsNuub4051 I got a 5 on mine!
@@GaurPand damm good job, im taking mine next week
bro same im struggling LMFAO

I really appreciate that !!!!
wow I really just learned what took my class 2 weeks to learn this in 30 minutes
This is late, but factsss. I spent weeks confused on this crap, but this man explains the whole unit in words I can understand in half an hour
They learn this in fourth grade in Greece (according to my Greek boss). Yikes
@@brits6251 greek kids learn normal models too? damn.
you explained the entirety of this unit exponentially better than my teacher. thank you so much!
literally one of the best explanations on UA-cam
Idk how I would have studied without this...thanks! AP Exam coming up real soon!
good luck!!!
How did you do?
Tis the mornin of the exam..hopefully I do good...
Good luck!
Taking it this year 👀 I hope you did as well as you wanted to!
Same but 2 years later
samezies
It's 2 years later. How did that test go?
multiplying for multiple events section was explained so well. dispelled all of my confusion, tysm mr. porinchak
getting a 5 on ap stats exam 4 u !!!!
Watched this video before my chapter test and now watching it again right before my exam. Much appreciated from ALL stats kids, keep it up! 💕
Muted my zoom classes and watched youtube for this entire chapter, watched this video for 30 mins and got a 90 anyway, thanks!
this clearly gave answers to all my questions. amazing review
9 hours before my exam and I just started studying :) it’s 2 am
go to bed
@@liammorris9823 good thing you let him know...11 months later
Why tf did I take this class
My thoughts exactly, I even signed up to take the exam
Literally me 💀💀
Hhhha thank you for the amazing video! I have my ap stat next Thursday so this helps a lot!!!
me too lmao
Good Luck!!!!!!!!!!!!!!!!
@@ojasnain6806 Good luck!!!!!
Really helpful here night before AP corona test
Hi Michael, thanks for a great video!!! I have my APs next week so wish me a good luck :)
you got it dude!
UGH TYSM U HAVE SAVED ME BLESS YOU!!
Very well made. Thank you so much!
Bros doing gods work
He doesn't get enough credit for teaching students in 30 minutes what they couldn't learn in class for one whole year
This video is so well explained ! Thank you
You sir are a lifesaver
wow this video has taught me more than an entire year in ap stat
Statistics is tricky than calculus due to it require attention to details naturally.
This video helped me soooooo much, thank you!
You are going to save my AP stats grade
2 hours before my AP Exam, wish me luck 🤝
Incredible! thank you so MUCH!
This lesson is very helpful for me doing AP Statistics
This is an amazing video! Thank you so much!
Woah. This video was awesome. Super helpful, thanks!!!
oh my god what a GODSENT
Great video, really helped me to understand probability. :)
i've exhausted all my boys and i must get that girl! lol. thanks for the help though
I read this comment and I was like “tf?!”, and then realized u were talking about the example lmao
"if I pick all 4 boys, I'm guaranteed, 100% chance, 3 out of 3, to get a girl on that fifth boy." 🤔

Probability of A and B = probability of A times the probability of B on the condition that A has occurred. This is true regardless of independence.
Michael Porinchak i understand. But at 11:11 you said if its conditional probability, then we can multiply prob of A and B only if independent
Ali Algabri hard to explain in words better if I could write it out. If you are trying to find the probably of A and B, if they are independent you can just multiple P(A)*P(B). If they are not independent or you don’t know them probability of A and B is P(A)*P(B|A)

your the man
got my prob test rmw...will edit and say how it goes ;)
please do!!!
Did u die
I’m going to take AP stats this year... is it super hard?
not if you work at it! It actually is a lot easier than other math classes! Hope you enjoy it.

hehe xd
Thank you soooooo much!!!!
you got it!!!!
A bit of a late comment, but awesome review!
Test today 🔥
Hour before the exam 😎
I like at 28:30 you made gross noises for the boys and good ones for the girls 🤣
Tell me why teachers can't teach like this. AP Stat is not as difficult as one may think.
nice
Great video but I think ur mic gave me heartworm lol
Ur better than khan academy he explains statistics all wrong
If you want my first born son, just ask.
This made me laugh!!!!!!!
I have a quiz in an hour oops
this guy makes everything so confusing
yikes sorry goal is to make it less confusing. Any constructive criticism on why its confusing to you would be appreciated.
