If two dices are rolled once, you would have a total number of 6*6=36 possibilities. To get a sum greater than 10: A) one of your dices could be showing a 5, the other a 6. That’s two possibilities. Dice A being the 5 or dice B being the 5. B) both of your dices could be showing 6s. That’s one possibility. So your overall possibility to get a sum greater than 10 is (1+2)/36 3/36=1/12 One twelfth.
