Question

Quizplus · Accepted Answer

Two events are independent if the occurrence of one event does not affect the probability of the other event. In other words, P(A | B) = P(A) or P(B | A) = P(B). Therefore, option C is the correct answer. The other options are incorrect. Option A implies simultaneous occurrence, which is not a defining factor for independence. Option B implies an impossible scenario since the probability of an event cannot be greater than 1. Option D is a blanket statement that does not provide any information.
