The probability of anything is the number of ways that it can happen that you would consider a success divided by the number of ways it can happen total -- successes and failures.
If you add up the number of total ways that you can roll a pair of dice you get 36.
So, to get at least a 6, you need the number of ways to get a 6 plus the number of ways to get 7 plus the number of ways to get 8...and so on up to 12. Then divide the total by 36.
