The size of the sample is 20C_5 or 15504 if the five kids is randomly chosen from a class of 20 students. An outcome of the selection process is the set of five kids selected.
<h3>What is permutation and combination?</h3>
A permutation can be defined as the number of ways a set can be arranged, order matters but in combination the order does not matter.
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 ![_{20}^{}\textrm{C}_5](https://tex.z-dn.net/?f=_%7B20%7D%5E%7B%7D%5Ctextrm%7BC%7D_5)
So the size of samples =
= 15504
Thus, the size of the sample is 20C_5 or 15504 if the five kids is randomly chosen from a class of 20 students. An outcome of the selection process is the set of five kids selected.
