Proposition: Characterization of Independent Events II

Let \(B\) be an event with the probability \(0 < p(B) < 1\). Another event \(A\) is independent from \(B\), if any only if the probability of the joint event \(A\cap B\) equals the product of the probabilities of \(A\) and \(B\):

\[p(A\cap B)=p(A)p(B).\]

If in addition, \(0 < p(A) < 1\), then \(B\) is independent from \(A\).
