The sample space for rolling two number cubes is shown below

1 2 3 4 5 6

1 1,1 1,2 1,3 1,4 1,5 1,6

2 2,1 2,2 2,3 2,4 2,5 2,6

3 3,1 3,2 3,3 3,4 3,5 3,6

4 4,1 4,2 4,3 4,4 4,5 4,6

5 5,1 5,2 5,3 5,4 5,5 5,6

6 6,1 6,2 6,3 6,4 6,5 6,6

Looking at the sample space, the outcomes where the sum is greater than 8 are

3, 6

4, 5

4, 6

5, 4

5, 5

5, 6

6, 3

6, 4

6, 5

6, 6

Thus, the correct answer is the last option
