Just a note to thank you for the magnanimity and generosity of making such an invaluable post in the interest of education. Yes this is fantastic and of immense benefit. Thank you sir!
I was confused with Jimmy picking the blue sweet first too but basically, the tree diagram is there to show you all the possible answers to the "First pick" as it can be blue or red. The probability of the blue is 7/10 and then we go from there to assume he picked a blue first so now it's 6/9. The probability of the first sweet being red is 3/10 and we go on from there to say that if he did pick a red it'll be 2/9.
Where in the problem does it say he ate a blue one 1st? I thought he'd just randomly picked one - or is it a given because the teacher just told us it was a blue one? BTW, your videos are very clear & very easy to understand. Thank you!
To do the drawing etc I used ActivStudio software by Promethean, which is usually used for smart boards in classrooms. To make the movie clip I used Camtasia.
Thanks for this, but the questions are complicated and tricky cause there was an earlier one i did. Well you did surprised me i thought it was the same one but this one is a bit different.
@LuffMileyCyrus he has only taken one sweet in the first pick so there will be 9 sweets left and then in the second pick he will take another sweet so there will be eight sweets left. so all up Jummy has only taken two sweets. there is 8 sweets left
can you please help me with my problem? 1. suppose you have five good (event G) fuses and two defective (event D) one have been mixed up. we select and test two fuses one by one, at random and without replacement. G1 event the 1st fuse is good D1 even the 1st fuse is defective G2 event the 2nd fuse is good D2 event the 2nd fuse is defective for some reason when I add up the numbers they dont come up to 1? can you please explain this problem
hang on. No where does it say that he ate the blue sweet first. is it because you are assuming that the chances of him picking a blue sweet first is 70% that we can say that he probably picked a blue first and ate it. Question makes no reference to sweet colour eaten.
You change the question mid way through and don’t show the answer to first situation. That’s not all that helpful (I know you can back track, but would be helpful to follow through first question before changing)
Omg finally i found this vid this helped me in my finals THANXXX!!!
btw who here is watching this in 2020
Not confusing at all.
Very helpful.

I was actually wondering how he knew if he took a blue one lol. Thank you
You sir are a legend
i didn't understand anything when my teacher thought me, but your video is awesome
thanks
Its 2022 , nd ive been struggling with drawing a dependable tree diagram but this really helped so much , thank uoo
Very helpful, thank you so much!
Both of your videos are excellent!! Thank you!!

Thank you. I love you.
Thank you so much! Totally refreshed my memory from early this year...god damn freshmen exams
Thank you for making this video!!!!!
He doesn't have 7 blues left, but the probability of B then R is calculated as 7/15, which doesn't mean that there are 7 blues.
Brilliant! Thanks again.
This would have explained it a hell of a lot better than my lecturer!
my teacher took 1 hour explaining this to me and i still dont get it. and now, after 5 minutes. i get the whole thing ,,,, amazing
So, you don't need to add them all up at the end?? I got 153/90 as my final answer.
It depends on the question
Thank u soo much ,this was soo helpful
Very helpful for my college stats class! Thanks

What program do you use?
This is good revision :D
u are the legend
@LuffMileyCyrus he has only taken one sweet in the first pick so there will be 9 sweets left and then in the second pick he will take another sweet so there will be eight sweets left. so all up Jummy has only taken two sweets. there is 8 sweets left
question, are the events disjoint?
BIG BRAIN MAN
hey fella ,,,, I like your accent :)
Thanks really helpes
he is goooooood !!!!!!!!!!!!!!
can you please help me with my problem?
1. suppose you have five good (event G) fuses and two defective (event D) one have been mixed up. we select and test two fuses one by one, at random and without replacement.
G1 event the 1st fuse is good D1 even the 1st fuse is defective
G2 event the 2nd fuse is good D2 event the 2nd fuse is defective
for some reason when I add up the numbers they dont come up to 1? can you please explain this problem
Miguel Salinas P(G1)=5/7,P(D1=2/7). Then P(G1G2) = 5/7*4/6, P(G1D2)=5/7*2/6, P(D1G2)=2/7*5/6, P(D1D2)=2/7*1/6. These probabilities add to 1.
Thank you! I dont know why i am having so much problem understanding this
Ron Barrow
how did you get 6/9 in the second pick?
cause he took one out
oh wait 4 year ago
@@chickenshopbossman5099 yeah that's why
oh wait 2 years ago

nah I remember this haha, had to revise on it the day before the test at night.
I came to here to learn how how to complete a tree diagram with three branches,not these basic probabilities,anyways thanks.
If hes picked a blue sweet and is left with 6/9 how does he have 7 blue sweet the next time he picks a blue.
Thanks
hahahaaaa this question came on my paper GCSE unit 1 lool
hang on. No where does it say that he ate the blue sweet first. is it because you are assuming that the chances of him picking a blue sweet first is 70% that we can say that he probably picked a blue first and ate it. Question makes no reference to sweet colour eaten.
storm3698 I'm sure he got that wrong as it's supposed to be 6 over 9 as she ate it. He made a mistake!!
Clara Solis thanks x
yes it does
Nevermind - I think i get it!
o bhai volume itna cum kyon hai? kuch sunayi nahi deraha
You change the question mid way through and don’t show the answer to first situation. That’s not all that helpful (I know you can back track, but would be helpful to follow through first question before changing)
it has bad sound volume
yo
Huh
My teacher disliked this because he can teach better than her :)
too quiet
This was really confusing, i have so many questions for this that dont make sense
