If P(A / B) = P(A), then P(A ∩ B) / P(B) = P(A) which can be simplified to P(A ∩ B) = P(A) * P(B). This is the definition of independent events, where the probability of the intersection of the events is equal to the product of their individual probabilities. Therefore, events A and B are independent.

If P(A / B) = P(A), Then Events a and B
