Compound Events

A compound event, not a riot that occurs on prison grounds, is an event that can be described in terms of simpler events.

A compound event will often, but not always, involve multiple experiments. Outcomes that result from combining two experiments are written like ordered pairs:

(outcome of first experiment, outcome of second experiment).

For instance, if Dr. Frankenstein tried bringing his creation to life AND curing its acne in one fell swoop, he would be engaging in a compound event.

Sample Problem

If we roll a die and flip a coin, the sample space is

{(1, H), (1, T), (2, H), (2, T), (3, H), (3, T), (4, H), (4, T), (5, H), (5, T), (6, H), (6, T)}.

"Rolling an even number and landing a head on the coin flip" is a compound event, since this event can be described in terms of the two simpler events "rolling an even number" and "landing a head on the coin flip."
