If you have more than one question you need to make separate posts.
Each roll has 12 possibilities, so there are `12 times 12 times 12 = 1728` different number of rolls.
Since the first 10 must be on the third roll, there are 11 possibilities for each of the first and second rolls, with 1 possibility (a 10) on the third roll. This gives `11 times 11 times 1= 121` different rolls. This means the probability is given by
`121/1728 approx 0.07002 = 7.002%`
The probability is `121/1728` .
