Best ResponseYou've already chosen the best response.1Two events A and B are independent events iff P(A and B) = P(A) x P(B).

Best ResponseYou've already chosen the best response.1In your question, P(not A) = 0.25 and the P(not B) = 0.2 and P(not A and not B) = 0.95. P(not A) x P(not B) = 0.25 x 0.2 = 0.05 = P(not A and not B) ∴ A and B are independent events.

Best ResponseYou've already chosen the best response.0i thought B was independent if P(AB) = P(A'B)
