Then the formula of conditional probability provides a way to compute the joint probability P(A ∩ B ) Conditional Probability 2 events: P(A ∩ B ) = P(B ) × P(A|B ) General Multiplication Rule More than 2 events: P(∩n=1 Ai ) = P(A1 ) × P(A2 |A1 ) × P(A3 |A1 ∩ A2 ) i × · · · × P(An |An−1 ∩ · · · ∩ A...
