Conditional probability is the probability that B will occur given that A has occurred. It is denoted by P(B | A).

The conditional probability of event B given event A, P(B | A), is given by

If events A and B are independent, then what is P(A | B)? Since the probability of event B occurring is not dependent on event A, P(A | B) = P(A). Our definition of independent events can be written more formally now.

Two events A and B are independent events if P(A | B) = P(A) or if P(B | A) = P(B).
