14. Which of the following statements is correct given that the events A and B 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 15. If P(A) = 0.20, P(B) = 0.30 and P(A and B) = 0.06, then A and B are: (A) mutually exclusive events (B) dependent events (C) complementary events (D) independent 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 %3D %3D _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 (D) P(A/B) = P(A) (E) none of the above _18. If A and B are mutually exclusive then: (A) P(A/B) = 0 (B) P(A/B) =P(B) (C) P(A or B) = 0 (D) P(A/B) = P(A) (E) none of the above %3D %3D
