Question

Quizplus · Accepted Answer

Two events A and B are mutually exclusive if they cannot occur at the same time, which implies that the probability of both events occurring together is zero, i.e., P (A and B) = 0. Therefore, among the given options, only option D satisfies this condition and is the best choice.
