A)
1) probability that exactly 4 of these cards are Aces=4C4*48C1/52C5 = 0.000018 or 0.0018%
2) probability that all five of these cards are Spades. = 13C5/52C5 = 0.000495 or 0.0495%
3) probability that exactly 4 of these cards are face
cards = 12C4*40C1/52C5 = 0.007618 or 0.7618%
4) probability of selecting exactly 2 Aces and exactly
2 Kings = 4C2*4C2*44C1/52C1 = 0.000609 or 0.0609%
5) probability of selecting exactly 1 Jack = 4C1*48C4/52C5 = 29.9474%
B)
1) probability of drawing either a jack or a ten = (4+4)/52 = 8/52 = 2/13
2) probability of drawing either a jack or a club = (4+13-1)/52=16/52=4/13
