Algebra II 10. 4: Find Probabilities of Disjoint and Overlapping Events HW: p. 710 (8 – 38 even) Chapter 10 Test: Thursday

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)

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

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%

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) = ______.
