GIVEN it's not a face card or an ace...
drawing a black seven out of a standard 52 card deck
52 - 4aces - 12face cards = 36 possibilities P = 2/36 = 1/18 *
drawing a 3 out of a standard 52 card deck 4/36 = 1/9
rolling a sum of 4 on two fair six sided dice. P = 3/36 = 1/12
rolling a sum of 11 on two fair six sided dice. P = 2/36 = 1/18 *
rolling a sum of 7 on two fair six sided dice. P = 6/36 = 1/6
