What is the combination formula?
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by:
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this problem, 3 countries are skipped from a set of 12, hence the number of ways is given by:
[tex]C_{12,3} = \frac{12!}{3!9!} = 220[/tex]
