Quizplus · Accepted Answer

The events are mutually exclusive because a person's birthday cannot be in May and not in May at the same time. The probability that a person's birthday is not in May is $\frac{365 - 31}{365} = \frac{334}{365}$, since May has 31 days and there are 365 days in a year (ignoring leap years).
