Step-by-step explanation:

So in order to get this answer you want to use the combination formula which is $\frac{n!}{(n-r)!r!}$

Now you want to use the numbers given to you in the problem which is ₈C₂ and plug those into the equation

so your going to have something looking like this $\frac{8!}{(8-2)!2!}$ now if you have a calculator nearby and you plug in ₈C₂ your going to get 28 which is the answer.
