Question

A team of five kids is randomly chosen from a class of 20 students. An outcome of the selection process is the set of five kids selected. What is the size of the sample space?

Answer 1

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.

What is permutation and combination?

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 $_{20}^{}\textrm{C}_5$

So the size of samples = $_{20}^{}\textrm{C}_5$ = 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.
