An experiment consists of rolling two fair number cubes. What is the probability that the sum of the two numbers will be 8? Express your answer as a fraction in simplest form.

ⓐ- 5/36
ⓑ- 1/9
ⓒ- 36/5
ⓓ- 31/36



I know that the answer is A, they give us the answer but we need to provide work and I don't understand how we get the answer.



Answer :

2-6, 3-5, 4-4, 5-3, 6-2 are all the possible number permutaions that the sum is 8 on two fair dice. There are only 5 ways to make 8. the total number of possible number permutations you would get by squaring 6 to get 36. your answer would then be A. 5/36
