Didn't you say 2 sweets are taken out at random, how come you deducted only one sweet from the tree diagram in the conditional bit?

[laibaimran]

I wish you were my math teacher.
I would have had A*s.
But then, the world is not a wish granting factory.

I have my S1 exam tomorrow, i've (no joke) learned more in about an hour with these videos than in three months with my teacher ... thank you so much !

Hi, what if order is not important let's say. P(RB) and P(BR) are the same right?

[tashab]

This video was very helpful although how come you don't cancel down any of the fractions at the end? Aren't you meant to?

[mahamkhalid]

Having trouble to find any videos for finding mean ans s.d by coding method!
help!!

[ramink.r]

for the last question, why can you not do 1- probablity of getting both blue and red?

[nauman.ashraf.]

for part iii) @ 5:05 the question asks for at least one red sweet so why do you add P(2R). Shouldn't it only be P(R, B)+P(B, R) ?

[halimabegum]

im so glad i found you. thank you so much!

[jiayong]

for the last question, the answer should be 15/28 not 30/56
