problem solving (Sample Space)

For maths we have been doing sample spaces, a sample space is a list of possible outcomes. For a final question we had to explain a answer to a question on our blog. Here is the question:


And here is the explained answer:

The answer is no because it would not be fair because the sample space for two six sided dice is
{1-1,1-2,1-3,1-4,1-5,1-6,2-2,2-3,2-4,2-5,2-6,3-3,3-4,3-5,3-6,4-4,4-5,4-6,5-5,5-6,6-6}
and a 12 sided die is
{1,2,3,4,5,6,7,8,9,10,11,12}.

If you don't understand that here is it simplified:
It is not fair because you can't role a one and it is harder to role doubles and there are more combinations for seven than any other number. Where as on a 12 sided die there is a fair chance of it landing on any number.
