Suppose that a computer software company has 30
programmers. use factorials to write the number of different ways
they couldselect a group of 6 of the programmers to work on a
particularproject.

Step-by-step explanation:

Given : The total number of programmers in the company = 30

The company wants to select a group of 6 programmers to work on a  particular project.

Since the order of selecting them does not matters , therefore we use combinations.

The number of combinations of r things taken from n things is given by :-

here, n= 30 and r= 6

So the number of different ways to form they could select a group of 6 would be

i.e. Total ways =593775

In terms of factorials , the number of total ways to form they could select a group of 6 is .

468
