Two events are independent if the occurrence of one does not affect the probability of the occurrence of the other. This means they do not have to be mutually exclusive (A is incorrect), their probabilities do not have to sum to one (B is incorrect), and the probability of their intersection is not necessarily zero; instead, it is the product of their individual probabilities (C is incorrect).
