Question

A pair of number cubes is tossed. The total number of dots on the two top faces is 6. What is the total of the dots on the bottom faces of the pair of number cubes?

Answer 1

Hi Humaira

 

One of the interesting things about dice is that opposite sides add up to 7.

So if you see a 1 on one side then 6 is on the other.

 

To get a 6, we can have the following combinations

1 and 5

2 and 4

3 and 3

 

If we have 1 and 5, the numbers on the opposite side are 6 and 2, for a total of 8

If we have 2 and 4, the numbers on the opposite side are 5 and 3, for a total of 8

If we have 3 and 3, the numbers on the opposite side are 4 and 4, for a total of 8.

 

So if we roll two dice and get 6, the number of dots on the opposite sides of the two dice is 8.
