Question

A diner offers a choice of two side items from the list with each entry. Of 8 sides are available how many ways can two items be selected? a. 15 c. 30 b. 28 d. 56

Answer 1

D. 56

Answer 2

you are being asked for "8 choose 2" sometimes written as
\[_8C_2\] or \[\binom{8}{2}\] and computed via
\[\binom{8}{2}=\frac{8\times 7}{2}\]
which (sorry) is not 56

Answer 3

Oh wait, I see what I did. I screwed that up a little bit. It's not 56.

Answer 4
