Think about it...

Can you flip both heads and tails and the same time on the same coin?

Can you roll one die and get an even number and a prime number on the same roll?

Can Batman and Bruce Wayne be seen in the same room at the same time?

Can Batman and Catwoman be seen in the same room at the same time?

Two events are considered mutually exclusive if they cannot occur at the same time.

MIXED PRACTICE - First determine if the events described are Mutually Exclusive or not. Then find the probability.

Multiple Choice

You roll 1 die 1 time. What is the probability you roll a number less than 4 OR an odd number?

• Not mutually exclusive,

  P(E) = 0.667

• Not mutually exclusive,

  P(E) = 1

• Mutually exclusive,

  P(E) = 0.667

• Mutually Exclusive,

  P(E) = 0.5

Multiple Choice

You roll 1 die 1 time. What is the probability you roll a number greater than 4 OR a 3?

• Not mutually exclusive,

  P(E) = 0.5

• Not mutually exclusive,

  P(E) = 0.333

• Mutually exclusive,

  P(E) = 0.5

• Mutually Exclusive,

  P(E) = 0.333

Multiple Select
