Question

11 POINTS!
4 students are assigned to give presentations. How many different ways can the teacher order the student presentations?

Answer 1

The first presentation can be given by any one of the 4 students.
Then the second presentation can be given by any one of the remaining 3.
Then the third presentation can be given by either one of the remaining 2.
Then the 4th presentation has to be the 1 student who's left.

So they can give their presentations in

                     (4 x 3 x 2 x 1)  =  24 different orders.

Answer 2

The teacher ordered the students in 24 ways.

What is the arrangement?

An arrangement (or ordering) of a set of objects is called a permutation.

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

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

4 students are assigned to give presentations.

4 students can be arranged in 4! ways.

The number of different ways can the teacher order the student presentations is;

$=4!\\\\= 4\times 3\times 2\times 1\\\\=24$

Therefore option 3 is correct.

The teacher ordered the students in 24 ways.
