Webb22 juni 2024 · Since events A and B are independent if P (A B) = P ( A ), it follows from the above formula that events A and B are independent if and only if: P ( A ) x P ( B ) = P (A ∩ B) So if we know that P ( A ) = 0.5, P ( B ) = 0.6 and P (A ∩ B) = 0.2, without knowing anything else we can determine that these events are not independent.
