The probability is zero. The largest possible sum on two dice is 12.
Two standard dice cannot have a sum greater than 12. The probability, then, of getting a sum greater than 15 is zero.
Zero. The minimum value of two dice being rolled is two.
With two normal six-sided dice, the maximum sum can only be 12 (6 x 2 dice), so there is zero probability of rolling a sum that adds to 16.
There are 36 permutations of two dice. Of these, 9 have a sum of 5 or 6, so the probability of rolling a sum of 5 or 6 on two dice is 9 in 36, or 1 in 9, or about 0.1111.
You can't get 14 with two regular six-sided dice ! The highest you can get with one throw is 12.
There are 36 permutations of two dice. Only one of them has a sum of two. Then probability, then, of rolling a sum of more than two is 35 in 36, or about 0.9722.
Assuming these are regular dice, the probability is 1.
Of the 36 possible outcomes of a throw of two dice, all but two result in a sum other than 3. So Prob(Not a three) = 100*34/36 = 94.44... %
35 in 36, or about 0.9722
