Answer:
There are 17,418,240 different ways to choose the teams.
Step-by-step explanation:
Arrangements of n elements:
The number of possible arrangements of n elements is given by:
[tex]A_{n} = n![/tex]
In how many different ways can the teams be chosen so that the number of employees on each project are as follows: 9, 4, 2?
This is:
Arrangement of 9 elements, followed by an arrangement of 4 elements followed by an arrangement of 2 elements. So
[tex]T = A_{9}*A_{4}*A_{2} = 9!*4!*2! = 362880*24*2 = 17418240[/tex]
There are 17,418,240 different ways to choose the teams.
