Then: Pr ( A ∪ B) = Pr ( A) + Pr ( B) − Pr ( A ∩ B) That is, the probability of either event occurring equals the sum of their individual probabilities less the probability of them both occurring . This is known as the addition law of probability . Proof 1 By definition, a probability measure is a measure .
