Theorem 3.9. For two events A and B, P (AnB) = P(A) .P (B IA), P(A) > 0 = P (B) . P(A \B), P(B) >0 } zwhere P(B |A) represents conditional probability of occurrence of B when the event A has already happened and P(A IB) is the conditional probability of happening of A, given that B has already happened.
