Hi there,

I am doing s1 for this jan and i am finding it very difficult to cope up. Especially for probability. I have a cgp buk but stil its not very gud at probability. Here is a question from my text buk which i cud not understand : -

Two events A and B are such that P(A) = 3/4 , P(B l A) = 1/5 and P(B' l A') = 4/7. By use of a probability tree or other wise find :

a) P(A and B)

b) P(B)

c) P(A l B)

In addition, can some 1 suggest a gud buk for probability plz.

Thanks!
