Question

The probability of event A is x, and the probability of event B is y. If the two events are independent, which condition must be true?

P(A|B) = y

P(B|A) = x

P(A and B) = x + y

P(A and B) = xy

Answer 1

to calculate the probability of both happening independent probabilities are multiplied

Answer 2

so which option do you think is correct?
