  1. Draw 3 cards without replacement from a standard 52 card deck. • What is the probability that: • They are all red ? • At least one is black ? • They are all face cards ? • They are all red AND they are all face cards ? • They are all red OR they are all face cards ? • They are all red IF they are all face cards ? answer answer answer answer answer answer
