Webb5 jan. 2024 · Example 1: What is the probability of rolling a dice and getting either a 2 or a 5? Solution: If we define event A as getting a 2 and event B as getting a 5, then these two events are mutually exclusive because we can’t roll a 2 and a 5 at the same time. Thus, the probability that we roll either a 2 or a 5 is calculated as:
