If an event has three possible outcomes, A, B, and C, and the probability of event A occurring is 0.20, the probability of event B occurring is 0.20, the probability of event C occurring is ________.

Question

Quizplus · Accepted Answer

The sum of the probabilities for all possible outcomes must add up to 1. If the probabilities of A and B occurring are both 0.20, then the sum of those probabilities is 0.40. Therefore, the probability of event C occurring must be 1 - 0.40 = 0.60.
