What is the probality of rolling a sum of 5 if two regular 6 -sides number cubes are rolled

Dmitry [639]

Each die has six numbers, the total number of possible combinations is 6 * 6 = 36

The combinations in which you can get a sum of 5 are: 1 &4, 2 & 3, 4 &1, 3 &2

There are 4 different combinations of getting a sum of 5.

The probability would be 4/36, which reduces to 1/9
