Answer 1

Hey there :)
The magic number is 7.
Seven is the most likely number to come up when you roll a pair of numbered cubes.

So if one person wins on 7,
it would be unfair to give the other person any other value but 7.

Answer 2

The further away we get from 7 in each direction gives us equally likelihood.

So for example, one above 7 is 8, and one below 7 is 6.
So the game would be fair if one person got 6 and the other had the 8.

Answer 3

Or three below 7 is 4 and three above 7 is 10.
So the game would be fair if one person got 4 and the other had 10.

Answer 4

Use that information to figure it out :D
Come on marieeee you can do it!
