A standard deck of cards is being used to play a game of blackjack. There are four suits (hearts,
diamonds, clubs, and spades), each having 13 faces (ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, jack, queen,
king), making a total of 52 cards. This complete deck is thoroughly mixed, and you will receive
the first 2 cards from the deck without replacement. In the game of blackjack the picture cards
(jack, queen, and king) count as 10 and the ace counts as either 1 or 11. All other cards are
counted at face value so a 2 counts as 2 and a 10 counts as 10. Blackjack is achieved if the first 2
cards given to you total 21. What is the probability of getting dealt a blackjack?
a)
The probability is somewhere between .0 and .0238
b)
The probability is somewhere between .0239 and .0279
c)
The probability is somewhere between .0280 and .0477
d)
The probability is somewhere between .0478 and .0579
e)
The probability is somewhere between .0580 and 1.0
The probability is somewhere between .0478 and .0579
