What is multiplication rule?
Multiplication rule: The probability that two events both occur equals the probability of the first times the conditional probability of the second given the first: P(A and B) = P(A) x P(B | A). For independent events it reduces to P(A) x P(B).
Multiplication rule: an example
Drawing two aces in a row without replacement: (4/52) x (3/51), about 0.0045.
