If A and B are independent events, show that A'and B are also independent. [Hint: First establish a relationship between P(A'N B), P(B), and P(A N B).] P(B) = P(A'N B) + --Select- v = P(B) - P(A N B) --Select--- Since A and 8 are independent, we have the following. P(A'N B) = P(B) - -Select--- v P(A'N B) = [1 - P(A)](-Select- V P(A'N B) = --Select--- V Thus, A' and B are independent.
