Suppose that the probability of event A is 0.2 and the probability of event B is 0.4. Also, suppose that the two events are independent. Then P(A|B) is:
A) P(A) = 0.2
B) P(A) / P(B) = 0.2/0.4 = ½
C) P(A)P(B) = (0.2)(0.4) = 0.08
D) None of the above.

For independent events, the probability of event A given event B, P(A|B), is simply the probability of A, which is 0.2. This is because the occurrence of B does not affect the probability of A in the case of independent events.
