You can put this solution on YOUR website! if a single die is rolled twice in succession, what is the probability that the sum is
(a) greater than 7,
Greater than 7 pairs:
2/6;3/5;4/4;5/3;5/3;6/2
3/6;4/5;5/4;6/3
4/6;5/5;6/4
5/6;6/5
6/6
P(>7) = 16/36 = 4/9
================================
(b) an even number?
Ans: 18/36 = 1/2
