In how many different ways can a pair of dice be rolled to obtain a total of 10?
The highest number on a single "die" is 6.
Since we want to get a total of 10 on the roll, we need to subtract from 10 every value possible on a single "die".
Once we reach
Realize that 7 is not a number that we have. We can't roll a combination of 3 and 7. Therefore, we have reached all of our possibilities.
