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 [tex]_{20}^{}\textrm{C}_5[/tex]
So the size of samples = [tex]_{20}^{}\textrm{C}_5[/tex] = 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.
