While playing a certain dice game, Chris wins if the sum of the two dice is 7, at which point the game is over. If the game allows Chris three rolls in an attempt to win, what is the probability that Chris will win? Choices:	A) 1/2	B) 17/36	C) 91/216	D) 11/36	E) 25/216
Total outcomes possible: 36   Total outcomes possible with sum 7: 6   Probability to win when rolled once = 6/36   Probability not to win when rolled once = 30/36 = 5/6   Probability to win in three attempts= 1- Probability will not to win in all three attempts   = 1- (5/6* 5/6*5/6)   = 91/216   Answer is 91/216.
