Question 7: 10 pts

Answer 1

The teacher ordered the students in 24 ways.

We have given that the total number of students is 4.

4 students are assigned to give presentations.

We have to find the arrangement of the 4 students.

What is the arrangement?

An arrangement (or ordering) of a set of objects is called a permutation. (We can also arrange just part of the set of objects.)

In a permutation, the order that we arrange the objects n is important.

4 students can be arranged by 4! ways.

$4!=4*3*2*1\\ =12*2\\=24$

Therefore option 3 is correct.

The teacher ordered the students in 24 ways.
