Two dice are rolled. Find the probability of rolling a sum greater than 6.

Confused on how to work this but...

Wouldn't the probability be just .71?

Possible outcomes and probabilitiy

2 1/36

3 2/36

4 3/36

5 4/36

6 5/36

7 6/36

8 5/36

9 4/36

10 3/36

11 2/36

12 1/36

so you would add the probability of all the possible outcomes greater than 6 which is 21 and divide that by the remaining possibilities? 15/21 = .71? or 71%?
