Or if we said that the probability of A and B is equal to the probability of A times the probability of B, then these would also mean they're independent. We know that this one's true. The probability of A and B is one-sixth, and the probability of A times the probability of B is one-half times one-third, which is one-sixth. 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.
