Answer:

13.8%

Explanation:

I have created a table that shows all of the possibilities that two die's can roll when summed up. If we count all of these possibilities we can see that there are a total of 36 outcomes. From all of these outcomes we can also see that only 4 outcomes sum up to be a total of 5. Therefore, we have to divide the number of times 5 is a possibility by the total number of outcomes to get the probability of actually getting a sum of 5.

5 / 36 = 0.138 ... multiply by 100 to get percentage

0.138 * 100 = 13.8%
