Explanation / Answer

Sol #30:

In logic and probability theory, two events are mutually exclusive or disjoint if they cannot both be true. Or one cannot be true if the other one is true.

In this case they are not mutually exclusive as they both can be true.

so the events A and B are not mutually exclusive.
