a is any event combining two or more simple events.
simple event
rare event
mutually exclusive event
compound event

Explanation:

A compound event is defined as an event that combines two or more simple events. A simple event is a single outcome (e.g., rolling a 3 on a die). A rare event is one with a very low probability. Mutually exclusive events cannot occur at the same time (e.g., flipping a coin and getting heads or tails simultaneously is impossible). But when we combine multiple simple events (e.g., rolling an even number on a die which is combining rolling a 2, 4, or 6 - simple events), it's a compound event.

Answer:

compound event
