If events A and B are independent, what must be true?
A.) P(AB) = P(B)
B.) P(A/B) = P(A)
C.) P(A) = P(B)
D.) OP(AB) = P(BIA)

Using conditional probability, it is found that the correct statement is:

B.) P(A/B) = P(A)

Conditional Probability

In which

If two events, A and B, are independent, we have that:

Hence:

Hence, option B is correct.
