What is Meant by Conditional Probability?

In probability, the conditional probability is defined as the probability of one event that has occurred in relation to the one or more events. Assume that A and B are the two events in a sample space, then the conditional probability of event A given event B is given by

P (A| B) = P (AB) / P(B), where P(B) >0

Similarly, the conditional probability of event B given event A is given by

P (B|A) = P (AB) / P(A), where P(A) >0
