Question

1. what does a compound event in probability involve?

a. the sum of probabilities of two events
b. an impossible outcome
c. the combination of two or more simple events
d. a single outcome from one event

Explanation:

A compound event in probability is defined as the combination of two or more simple events. Option a is incorrect as it refers to a sum of probabilities (which might be related to mutually - exclusive events formula but not the definition of a compound event). Option b is wrong because an impossible outcome is an event with probability 0 and not related to the compound event definition. Option d describes a simple event, not a compound one.

Answer:

C. The combination of two or more simple events
