WebbIF P (A)*P (B) = P (A and B) THEN A and B are independent events, otherwise, they are dependent events. As you’ve seen, the last three rules that we’ve introduced (the Complement Rule, the Addition Rules, and the Multiplication Rule for Independent Events) are frequently used in solving problems. WebbSince the probabilities of O, B, and AB together sum to 0.44 + 0.1 + 0.04 = 0.58, the probability of type A must be the remaining 0.42 (1 – 0.58 = 0.42): Probability Rule Two This example illustrates our second rule, which tells us that the probability of all possible outcomes together must be 1.
