PROBABILITY & COMPOUND EVENTS #1

 

 

Directions:  A compound event represents a series of events happening at the same time, or in order.  To calculate the probability of compound events, you can multiply the probabilities of each individual event.  Depending on your teacher’s preference, you can write this probability as a fraction or a decimal.

 

Examples:
