Event X and event Y are independent events. The probability of X is 0.2 [P(X) = 0.2] and the probability of Y is 0.5 [P(Y) = 0.5]. The joint probability of X and Y [P(X, Y] is closest to:
A is correct. Given that X and Y are independent, their joint probability is equal to the product of their individual probabilities. In this problem, we calculate 0.2 × 0.5 = 0.1.
