Thomas's favorite colors are blue and green. He has one blue shirt, one green shirt, one blue hat, one green scarf, one blue pair of pants, and one green pair of pants. Thomas selects one of these garments at random. Let A be the event that he selects a blue garment, and let B be the event that he chooses a shirt. Which of the following statements are true? And they all, let's see, before I even read them, they all deal with probability of event A, probability of event B, probability of B given A, probability of A given B, probability of A and B. So actually, let's just calculate these things ahead of time before we even look at these right over here.
