Question

Two standard dice are rolled. What is the probability that the total of the two dice is less than 6?

Answer 1

The sample space has 36 possible combinations of numbers. These can be set out in column form as follows:
6,6 5,6 4,6 3,6 2,6 1,6
6,5 5,5 4,5 3,5 2,5 1,5
6,4 5,4 4,4 3,4 2,4 1,4
6,3 5,3 4,3 3,3 2,3 1,3
6,2 5,2 4,2 3,2 2,2 1,2
6,1 5,1 4,1 3,1 2,1 1,1
Now you need to count the number of outcomes where the total of the two numbers is less than 6. Then divide that total by 36 to get the required probability.
