Question

A pair of standard dice is rolled. Find the probability that the sum of the two dice is less than 13

Answer 1

For standard number cubes (1-6), the maximum answer possible is 12

(=6+6)

So, all possible answers are less than 13, giving a probability of 100%.

Answer 2

As the largest number possible outcome is (6,6) , and their sum is 12 , less than 13 , we conclude that all the pairs will have sum less than 13.

Thus all the pairs are in the favourable outcomes , and the probability is 1
