In Problems 41 and 42, two balls are drawn in succession from an urn containing m blue balls and n white balls (m ≥ 2 and n ≥ 2). Discuss the validity of each statement. If the statement is always true, explain why. If not, give a counterexample.

(A) If the two balls are drawn with replacement, then P(B₁ W₂) = P(W₂|B₁). (B) If the two balls are drawn without replacement, then P(B₁ W₂) = P(W₂ B₁).
