Exercise 2.3

1.
Six cards with the numbers 1 through 6 on them are well shuffled and two cards are dealt (without replacment). Find the probability that the sum of the numbers on the two cards is 7. Note order is not important here. For example, the hand with cards 1,2 in it is the same as the hand with cards 2,1. In the sample space there are 15 elements. List them. Then find the probability that the sum of the numbers on the two cards is 7. Why is your answer different from the craps game answer?
