1. Algebra II 10.4: Find Probabilities of Disjoint and Overlapping Events HW: HW: p.710 (8 – 38 even) Chapter 10 Test: Thursday

2. Overlapping Events Two events are overlapping if they have one or more outcomes in common. P(A or B) = P(A) + P(B) – P(A and B)

3. Disjoint Events Two events are disjoint, or mutually exclusive, if they have no outcomes in common. P(A or B) = P(A) + P(B) A B

4. Events A and B are disjoint. Find P(A or B). 1.) P(A) = 0.2, P(B) = 0.3 2.) P(A) = 34%, P(B) = 45%

5. Find the indicated probability. 1.) P(A) = 47%, P(B) = 21%, P(A or B) = 0.25, P(A and B) = ____________. 2.) P(A) = 0.25, P(B) = 0.32, P(A or B) = 0.45, P(A and B) = ____________.

6. A card is randomly drawn from a standard deck of 52 cards. Find the probability of drawing the indicated card. 1.) A heart or a diamond 2.) A spade or an even card

7. A card is randomly drawn from a standard deck of 52 cards. Find the probability of drawing the indicated card. 3.) A 6 or a 7 4.) An ace or a spade

8. A card is randomly drawn from a standard deck of 52 cards. Find the probability of drawing the indicated card. 5.) An ace and a spade 6.) A face card and a 4 7.) A spade and an even card
