Example 3: If one card is drawn from a deck, find the probability of getting (a) a club or 0.25 P (a club) = = = (b) a 4 and a club (a 4 and a club) = = 0.019 P ≈ Example 4:Three equally qualified runners, Mark, Bill, and Alan, run a 100-meter sprint, and the order of finish is recorded. (a) Give a sample space S. S = {MBA, MAB, BMA, BAM, AMB, ABM} (b) What is the probability that Mark will finish last? E = {BAM, ABM} or 0.333 P (E) = = = ≈ Ch5.2 The Addition Rules and Complements Objective A: Addition Rule for Disjoint (Mutually Exclusive) Events Event A and B are disjoint (mutually exclusive) if they have no outcomes in common. Addition Rule for Disjoint Events If and are disjoint events, then.
