Probability Independent Events

Compound Event

A compound event is made up of 2 or more simple events.

Independent Events

Are events where the outcome does not affect the outcome of the other event

How do we find (solve) probability of compound events

P = (1st event) *(2nd event)

Lets try an example together

A coin is tossed and the spinner is spun. Find the probability of tossing heads and landing on the color red.

1/2 *1/4 =1/8
