have nonzero probabilities?
(A) A and B are always independent
(B) A and B cannot be both independent and mutually exclusive
(C) A and B are always mutually exclusive
(D) A and B can be both independent and mutually exclusive

(A) mutually exclusive events
(B) dependent events
(C) complementary events

16. Two events A and B are said to be mutually exclusive if:
(A) P(A/B) = 1
(B) P(B/A) = 1
(C) P(A and B) = 0
(D) P(A and B) = 1
(E) none of the above
17. If A and B are independent then:
(A) P(A/B) = 0
(B) P(A/B) =P(B)
(C) P(A and B) = 0
