Lipid Fried Chicken offers a jumbo special with a choice of three side dishes from eight different side dishes on the menu. Assuming you must choose three different side dishes, how many different possibilities are there for your side dish selection?

The answer is C(8,3)

My question is why its a combination why not permutation ?

Thanks.

because there is no ordering to the set of side dishes


chicken with fries, corn, slaw  is the same meal as chicken with corn, slaw, fries

your past several questions have mostly been about English wording and not really the math of it.

as I said in a previous question, there is no "system" for determining  permutation vs combination  based on English phraseology.


You just have to think about what is being asked.

if you rearrange letters, you get new words,  the ordering matters.
if you rearrange side dishes on your plate, you get the same meal, so ordering does not matter.
