WebP (A ∩ B) = P (A) × P (B A) = (3/10) × (7/9) = 0.2333 Union of A and B In probability, the union of events, P (A U B), essentially involves the condition where any or all of the events being considered occur, shown in the … WebMay 14, 2024 · By the definition of intersection, since X is an element of both P (A) and P (B), X is an element of P (A) ∩ P (B). Thus, every element of P (A∩B) is an element of P (A) ∩ P (B). Again without loss of generality, let set Y be an arbitrary element of P (A) ∩ P (B). By the definition of intersection, Y is an element of P (A) and Y is an ...
