What is the probability of rolling a sum of 8?

Answer 1

Answer:

  5/36

Step-by-step explanation:

There are 5 ways that a sum of 8 can be rolled:

  6,2  5,3  4,4  3,5  2,5

So, 5 of the 36 possibilities will give you that sum. The probability of rolling that sum is 5/36.

Answer 2

Using it's concept, it is found that there is a 0.1389 = 13.89% probability of rolling a sum of 8.

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, when two number cubes are rolled, there is a total of 6² = 36 outcomes.

Of those outcomes, 5 result in a sum of 8, which are (2,6), (3,5), (4,4), (5,3) and (6,2), hence the probability of rolling a sum of 8 is given by:

p = 5/36 = 0.1389 = 13.89%.
