lets make a list
assuming they have 2 cubes with 1-6 on them
combos are
1,1
1,2
1,3
1,4
1,5
1,6
2,1
2,2
2,3
2,4
2,5
2,6
3,1
3,2
3,3
3,4
3,5
3,6
4,1
4,2
4,3
4,4
4,5
4,6
5,1
5,2
5,3
5,4
5,5
5,6
6,1
6,2
6,3
6,4
6,5
6,6
and out of all of them (when you add them),
only 5 possible roles add up to 8
only 2 possible roles add up to 11
that means that if you rolled the max number of times, then 8 would come up 5 times, but 11 woule come up 2 times
so it is more probable to get an 8 than an 11
