Multiplication rule for counting
WebAddition Rule Formula. When calculating the probability of either one of two events from occurring, it is as simple as adding the probability of each event and then subtracting the probability of both of the events occurring: P (A or B) = P (A) + P (B) - P (A and B) We must subtract P (A and B) to avoid double counting!
