If two events are mutually exclusive, then the probability of either occurring is the sum of the probabilities of each occurring. Specific Addition Rule. Only valid when the events are mutually exclusive. P(A or B) = P(A) + P(B) Example 1: Given: P(A) = 0.20, P(B) = 0.70, A and B are disjoint WebJan 6, 2024 · P (A or B) = 174 ⁄ 132.
