Explanation / Answer

Mutually Exclusive Events. Two events are mutually exclusive if they cannot occur at the same time. Another word that means mutually exclusive isdisjoint. If two events are disjoint, then the probability of them both occurring at the same time is 0.

a. A surgeon can be a female also so this event is not disjoint

b. Republican can't be democrat hence this event is disjoint

c. A rated movie can have four stars so not disjoint

d. College graduate can be homeless so not disjoint.
