Ex 13.2, 6 Let E and F be events with P(E) = 3 5 , P(F) = 3 10 = and P (E F) = 1 5 . Are E and F independent? Two events A & B are independent if P(A B) = P(A) . P(B) Given, P(E) = 3 5 , P(F) = 3 10 & P(E F) = 1 5 Now, P(E) . P(F) = 3 5 3 10 = 9 50 & P(E F) = 1 5 = 10 50 Since P(E F) P(E) . P(F) , Therefore, E and F are not independent events
