There are 36 permutations of two dice. Of these, 15 add up to a sum greater than 7. The permutations are listed below, with the desired results bolded.

1 + 1 = 2

1 + 2 = 3

1 + 3 = 4

1 + 4 = 5

1 + 5 = 6

1 + 6 = 7

2 + 1 = 3

2 + 2 = 4

2 + 3 = 5

2 + 4 = 6

2 + 5 = 7

2 + 6 = 8

3 + 1 = 4

3 + 2 = 5

3 + 3 = 6

3 + 4 = 7

3 + 5 = 8

3 + 6 = 9

4 + 1 = 5

4 + 2 = 6

4 + 3 = 7

4 + 4 = 8

4 + 5 = 9

4 + 6 = 10

5 + 1 = 6

5 + 2 = 7

5 + 3 = 8

5 + 4 = 9

5 + 5 = 10

5 + 6 = 11

6 + 1 = 7

6 + 2 = 8

6 + 3 = 9

6 + 4 = 10

6 + 5 = 11

6 + 6 = 12

The probability, then, of rolling a sum greater than 7 with two dice is 15 in 36, or about 0.4167.

If six-sided dice are not what you are talking about, then please restate the question and be more specific about what you want to know.
