What is the definition of a compound event in probability?

A compound event in probability is an event that consists of two or more simple events. Simple events are the most basic outcomes that cannot be broken down further. A compound event can be formed by combining simple events using logical operations such as "and" (intersection) or "or" (union). For example: - If you roll a die, the simple events are the outcomes {1, 2, 3, 4, 5, 6}. A compound event could be rolling an even number, which includes the simple events {2, 4, 6}. - Another example of a compound event could be drawing a card from a deck and getting either a heart or a queen. This event combines the simple events of drawing any heart (13 outcomes) and drawing any queen (4 outcomes, but one of them is a heart, so it counts only once). In summary, a compound event is a combination of two or more simple events, and it can be analyzed using the rules of probability to determine its likelihood.
