Example 1

8. Mutually exclusive events are events that cannot occur at the same time.
Vocabulary

9. Addition Rules for Probability If two events A and B are mutually exclusive, the probability that A or B will occur is: P(A or B) = P(A) + P(B) If two events A and B are not mutually exclusive, the probability that A or B will occur is: P(A or B) = P(A) + P(B) – P(A and B)
Vocabulary

10. Determine whether the events are mutually exclusive or not mutually exclusive. Then find the probability: Keisha has a stack of 8 baseball cards, 5 basketball cards, and 6 hockey cards. If she selects a card at random from the stack, what is the probability that it is a baseball or a hockey card?
Example 2

11. Determine whether the events are mutually exclusive or not mutually exclusive. Then find the probability: Suppose that of 1400 students, 550 take Spanish, 700 take biology, and 400 take both Spanish and biology. What is the probability that a student selected at random takes Spanish or biology?
