So all of these are clearly true, so we can say that A and B are independent. The probability of A is independent of whether B has happened or not, and the probability of B happening is independent of whether A has happened or not. The outcome of events A and B are dependent on each other. No, that's the opposite of saying that they're independent, so we're not going to, we can cross that out. Probability of A and B is equal to probability of A times probability of B. We already said that to be true. One-sixth is one-half times one-third.
