Answer:
x = (180-147)/3
x = 11
Step-by-step explanation:
There are 5005 different groups
<h3>How to determine the number of groups?</h3>
The given parameters are:
Players, n = 15
Selected, r = 6
The number of groups is then calculated as:
![Group = ^{n}C_r](https://tex.z-dn.net/?f=Group%20%3D%20%5E%7Bn%7DC_r)
This gives
![Group = ^{15}C_6](https://tex.z-dn.net/?f=Group%20%3D%20%5E%7B15%7DC_6)
Apply the combination formula
![Group = \frac{15!}{9!6!}](https://tex.z-dn.net/?f=Group%20%3D%20%5Cfrac%7B15%21%7D%7B9%216%21%7D)
Evaluate the expression
Group = 5005
Hence, there are 5005 different groups
