Can you tell me how you did that? Just so I know?

beccab003 · Answer

I know how to solve these problems but I can't tell the difference between permutation and combination.

Sorry that was not the one that I was trying to say.

I was trying to say that since there are 5 people and are only 8 chairs, there will be at least three chairs left over. So maybe we can do: $$8! \div 3!$$

That is how I thought the equation was supposed to look like.

calculusxy · Answer

So did that work actually?

beccab003 · Answer

Oh I solved it. So it would be 6,720. Right?
