In the game of 21, the goal is to get exactly 21 points, or to get as close to 21 as you can, without going over. The point values are awarded as follows:
2 card: 2 points
3 card: 3 points
4 card: 4 points, etc.
Jack, Queen, King: 10 points
Ace: 1 or 11 points - whichever works best with the hand
A hand of cards is given, determine the number of points you already have. Then, assume that
you are given exactly one additional card. Determine the probability and odds of scoring
exactly 21 points, and determine the probability of scoring less than 21 and the odds of scoring
greater than 21 points.
Remember that when you are computing the probability and odds, the cards in your hand are no
longer in the deck. (4 points each)
