The addition rule applies when two mutually exclusive outcomes are possible. This means that only one of the outcomes can happen, and they cannot happen at the same time. The addition rule states that the probability of either of the outcomes occurring is equal to the sum of their individual probabilities. For example, the probability of rolling a 1 or a 6 on a single die is 1/6 + 1/6 = 1/3, because these are mutually exclusive outcomes.
