The addition rule of probability is used to find the probability that either one of two independent events will occur. It is often expressed as P(A or B) = P(A) + P(B) - P(A and B), where P(A and B) is subtracted to correct for the fact that it was counted twice if events A and B are not mutually exclusive.
