The n is 12 because there are 12 teams.
The r is 2 because there are only two options, it's either you'll win or lose in the eliminations.

Solution:

C(12, 2) =  \frac{n!}{r!(n-r)!}

             =  \frac{12!}{2!(12-2)!}

             =  \frac{12!}{2!10!}

             = 66

Therefore, there will be 66 elimination games.
