Multiplication Rule for Probability: If E E and F F are events associated with the first and second stages of an experiment, then P (E and F) = P (E) × P (F | E) P (E and F) = P (E) × P (F | E).

Conditional probability \(P(A|B)\) (probability of A given B) is the probability of event \(A\) knowing that \(B\) has occurred. In the context of conditional probability, \(P(A)\) is called a prior probability, \(P(A|B)\) is called posterior probability.
Solution. Problem. Let C1,C2, ⋯,CM C 1, C 2, ⋯, C M be a partition of the sample space S S, and A A and B B be two events. Suppose we know that. A A and B B are conditionally independent given Ci C i, for all i ∈ {1, 2, ⋯, M} i ∈ {1, 2, ⋯, M}; B B is independent of all Ci C i 's. Prove that A A and B B are independent. Solution. Problem.
