What is permutation and combination?

We have total number of students in a class = 20
An outcome of the selection process is the set of five kids selected.
A team of 5 kids choosen from a class of 20 students in [tex]_{20}^{}\textrm{C}_5[/tex]
So the size of samples = [tex]_{20}^{}\textrm{C}_5[/tex] = 15504
