Conditional probability formula 3 events
WebThe multiplication rule can be extended to three or more events. In the case of three events, the rule looks like this: P ( A ∩ B ∩ C) = P [ ( A ∩ B) ∩ C)] = P ( C A ∩ B) a × P ( A ∩ B) b But since P ( A ∩ B) = P ( B A) × P ( A) b: P ( A ∩ B ∩ C) = P ( C A ∩ B) a × P ( B A) × P ( A) b Example 4-5 http://www.stat.yale.edu/Courses/1997-98/101/condprob.htm
