julia-pushkina [17]

Answer:

There are 1,585,080 ways for her to select students and assign them to the jobs

Step-by-step explanation:

The order in which the students are selected is important, since different orderings means different jobs for each student selected. So the permutations formula is used to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

$P_{(n,x)} = \frac{n!}{(n-x)!}$

In this problem:

4 students selected from a set of 37. So

$P_{(37,4)} = \frac{37!}{(37-4)!} = 1585080$

There are 1,585,080 ways for her to select students and assign them to the jobs
