So now that we've figured out all of that, let's see if we can answer these questions. The probability of A given B equals the probability of A, and that does work out. Probability of A given B is one-half, and that's the same thing as the probability of A. The probability that Thomas selects a blue garment given that he has chosen a shirt is equal to the probability that Thomas selects a blue garment. Yep, that's exactly. So I guess the words are just rephrasing what they wrote here in, I guess, more mathy notation. So this is absolutely true.
