If you roll two fair six-sided dice, what is the probability that the sum is 5 or lower?

6 sided dice = 1,2,3,4,5,6
2 6 sided dice=1,1,2,2,3,3,4,4,5,5,6,6
5 or lower = 1,1,2,2,3,3,4,4,5,5 = 10

Probability is 10/12 because the 10 comes from the numbers from each dice that are 5 or lower.
The 12 comes from all the numbers from each dice added = 12.

= 10/12 

(hope this helps :/ )
