Question

Quizplus · Accepted Answer

Two events are independent if the occurrence of one event does not affect the probability of the other event occurring. This does not imply that they must be mutually exclusive, that their probabilities must sum to 1, or that the probability of their intersection is 0. Independence is about the lack of influence between the occurrences of the events, not about their probability measures directly.
