WebJan 5, 2024 · If A and B are not mutually exclusive, then the formula we use to calculate P(A∪B) is: Not Mutually Exclusive Events: P(A∪B) = P(A) + P(B) - P(A∩B) Note that P(A∩B) is the probability that event A and event B both occur. The following examples show how to use these formulas in practice. Examples: P(A∪B) for Mutually Exclusive Events
