Combination is when the order DOESN'T matter.
Permutation is when the order DOES matter
Does the order matter on this?

I don't know what it is. To me it's just a question I don't know how to do. The paper says probability. So which do I choose?

The order does not matter. 4 students chosen from a class. It would've stated it had to be in a specific order if it needed to.
