SpletIt implies. P (B) = P (A∩B)/P (A) = P (B A), which exactly means that B is independent of A. We see that two events A and B are either both dependent or independent one from the other. The symmetric definition of independency is this. (*) P (A∩B) = P (A) P (B). Two events A and B are independent iff that condition holds.
