Problem-4 (7 points): Craps is a popular dice game played in casinos. Write a program to play a variation of the game, as follows: Roll two dice. Each die has six faces representing values 1,2,, and 6 , respectively. Check the sum of the two dice. If the sum is 2,3 , or 12 (called craps), you lose; if the sum is 7 or 11 (called natural), you win; if the sum is another value (i.e., 4,5,6,8,9, or 10 ), a point is established.
