9.4 Compound Events

Front

What is a compound event in probability?

Back

A compound event is an event that consists of two or more simple events. For example, rolling a die and flipping a coin simultaneously.

Front

How do you calculate the probability of a compound event?

Back

To calculate the probability of a compound event, you can use the addition rule for mutually exclusive events or the multiplication rule for independent events.

Front

What is the definition of mutually exclusive events?

Back

Mutually exclusive events are events that cannot occur at the same time. For example, rolling a 1 and rolling a 2 on a single die.

Front

What is the definition of independent events?

Back

Independent events are events where the outcome of one event does not affect the outcome of another. For example, flipping a coin and rolling a die.

Front

How do you find the probability of two independent events occurring together?

Back

Multiply the probabilities of each event. For example, P(A and B) = P(A) * P(B).
