Answer

Question 7

Brief Explanations:

Disjoint events (mutually - exclusive) cannot occur at the same time. A card cannot be both a heart and a club simultaneously.

Answer:

C. disjoint events.

Question 8

Brief Explanations:

A probability can be 0 (for an impossible event), so the statement "A probability is always greater than 0" is incorrect.

Answer:

A. A probability is always greater than 0.
