Which of the following statements is correct if the events A and B have nonzero probabilities?
a. A and B cannot be both independent and disjoint
b. A and B can be both independent and disjoint
c. A and B are always independent
d. A and B are always disjoint

Question 2

Suppose P(A) = 0.60, P(B) = 0.85, and A and B are independent. The probability of the complement of the event (A and B) is:
a. .4 .15 = .060
b. 0.40 + .15 = .55
c. 1 - (.40 + .15) = .45
d. 1 - (.6 .85) = .490
