what the question states :

"Events A and B are such that:

p(A) = 5/12

p(A|notB)=7/12

P(A intersection B ) =1/8 "

Would I be correct if I assume that Not B refers to A ? , so then i can draw a probability tree.

Most likely "notB" means "event B did

**not**occur"

I would also advise you to draw a Venn diagram for this question. - Dec 1st 2011, 09:01 AMPlatoRe: Two events and a simple question

Oh how dumb of me -.-

I should have reasoned that out. Largest problem with probability=> reasoning simple things out.
