What is the probability of an event A given that event B has occurred? We call this conditional probability, and it is governed by the formula that P(A B) which reads "probability of A given B" is equal to the P(A intersect B)/P(B). We look at an example involving the probability of being an alcoholic given that one is a man.

Conditional Probability Formula: P(A
B) = P(A and B)/P(B)
