Which of the following statements is TRUE?

Select one:

a. If events A and B are independent and P(A) = 0.90 and P(B/A) = 0.50, then P(A n B) = 0.45.

b.

The probability of the union of two mutually exclusive events A and B is P(A U B) = 0.

c.

Assume that A and B are independent events with P(A) = 0.30 and P(B) = 0.50.

The probability that both events will occur simultaneously is 0.80.

d. If events A and B have non-zero probabilities, then they can be both independent and mutually exclusive.
