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 .

12/11c

or

12

c

11

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
