Which of the following statements is always true? A. It is always appropriate to use the classical method to determine the probability of each outcome of an experiment. O B. When computing the number of ways to randomly draw 5 marbles out of 20 marbles (without replacement) where the order does not matter, we should the permutation rule. O C. When two events A and B are mutually exclusive, then P(AnB) = P(A) + P(B). O D. When two events A and B are independent, then P(A|B9) = P(A), where BC represents the complement of B.
