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)

Multiple Choice

How do we find compound event?

• dividing simple events

• adding simple events

• multiplying simple events

• subtracting simple events

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
