Two events are mutually exclusive when the probability that both events happen equals the product of the probability that both events happen individually.
i.e. P(A and B) = P(A) x P(B)
Here, P(A and B) = 0.5 but P(A) x P(B) = 0.75 x 0.6 = 0.45
Therefore, the two events are not independent.
Two events are said to be mutually exclusive when P(A and B) = 0. Here P(A and B) ≠ 0.
Therefore, the two events are not mutually exclusive.
Therefore, option C is the correct answer.
