The outcomes for each number cube are 1, 2, 3, 4, 5, and 6 so the smallest possible sum for two number cubes is

1+1=2

and the largest possible sum is

6+6=12.
The outcomes for rolling a sum of 8 are

2+62+6,

6+26+2,

3+53+5,

5+35+3,

and

4+4.

There are then 5 possible outcomes for rolling a sum of 8.
If an event has more than 5 possible outcomes, it would then be more likely than rolling a sum of 8.
The smaller the sum is (such as a sum of 3 or 4) or the larger the sum is (such as a sum of 10 or 11), the fewer possible outcomes there are.
The sum with the largest number of possible outcomes is then the sum halfway between the smallest sum of 2 and the largest sum of 12, which is

2+122=142=7
The possible outcomes for a sum of 7 are

1+6,

6+1,

2+5,

5+2,

3+4,

and

4+3

so there are 6 possible outcomes for a sum of 7. There are then more possible outcomes for a sum of 7 than there are for a sum of 8.
An event that is more likely than rolling a sum of 8 is then rolling a sum of 7.
