So this is the probability of picking a blue shirt. So only one out of the six equally likely outcomes is a blue shirt. So this one right over here is going to be one over six. 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.
