Summary
abilities are also called marginal probabilities. A probability of an event given (conditioned on) another event is a conditional probability. The probability of an event A given an event B is denoted P(A | B). <span>The probability of both A and B occurring is the joint probability of A and B, denoted P(AB). P(A | B) = P(AB)/P(B), P(B) ≠ 0. The multiplication rule for probabilities is P(AB) = P(A | B)P(B). The probability that A or B occurs, o
