Define "success" as finding a car under the chosen cup. What is the probability of success for strategy A (don't switch) and strategy B (switch)? Strategy A: P(success) = 1 2 ; Strategy B: P(success) = 1 2 Strategy A: P(success) = 2 3 ; Strategy B: P(success) = 1 2 Strategy A: P(success) = 1 2 ; Strategy B: P(success) = 1 3 Strategy A: P(success) = 1 3 ; Strategy B: P(success) = 2 3
