Two events are mutually … WebP (B A) = P (A∩B)/P (A) From these formulas, we can derive the product formulas of probability. P (A∩B) = P (A B) × P (B) P (A∩B) = P (B A) × P (A) If A and B are independent events, then P (A B) = P (A) or P (B A) = P (B). If A and B are independent events, then P (A∩B) = P (A). P (B) So P (A B) = P (A). P (B)/P (B) = P (A)
