By this form of reasoning, we can arrive at the following law of probability: The probability that either of events A and B will occur, or that both of them will occur, is equal to the sum of their separate probabilities less the probability or their joint occurrence. Thus P ( A B ) = P ( A ) + P ( B ) P ( A B ) . 6
