General Permutation / Combination Question
I am trying to understand how to identify if a question is a permutation or combination question before apply the formulae.
I want to know how is this question a permutation;
How many ways can 6 people sit around a table?
thank you

It should just be a permutation of the objects, though the symmetry round the table would mean a bit of reasoning about how you handle the first person.
For nPr and nCr, its really just about whether the order of the objects matters.

Is on the simpler side,but quite well explained.
