Define in words mutually exclusive events.

Choose the correct answer below.

A.

Events A and B are mutually exclusive if all of the sample points in A are also in B or vice versa.

B.

Events A and B are mutually exclusive if A contains all sample points not contained in B and vice versa.

C.

Events A and B are mutually exclusive if A and B have no sample points in common.

D.

Events A and B are mutually exclusive if A and B contain exactly the same sample points.

Define the union of two events.

Choose the correct answer below.

A.

The union of two events A and B is the event that occurs if only one of A or B occurs on a single performance of an experiment.

B.

The union of two events A and B is the event that occurs if neither A nor B occurs on a single performance of an experiment.

C.

The union of two events A and B is the event that occurs if either A or B(or both) occurs on a single performance of an experiment.

D.

The union of two events A and B is the event that occurs if both A and B occur on a single performance of an experiment.

Define in words the complement of an event.

Choose the correct answer below.

A.

The complement of an event A is any event that has no sample points in common with event A.

B.

The complement of an event A is the probability of all sample points in event A.

C.

The complement of an event A is the event consisting of all sample points that are not in event A.

D.

The complement of an event A is the event consisting of exactly the same sample points that are in event A.
