<u>Answer</u>:
3003 number of 5-member chess teams can be chosen from 15 interested players.
<u>Step-by-step explanation:</u>
Given:
Number of the interested players = 15
To Find:
Number of 5-member chess teams that can be chosen = ?
Solution:
Combinations are a way to calculate the total outcomes of an event where order of the outcomes does not matter. To calculate combinations, we will use the formula![nCr = \frac{n!}{r!(n - r)!}](https://tex.z-dn.net/?f=nCr%20%3D%20%5Cfrac%7Bn%21%7D%7Br%21%28n%20-%20r%29%21%7D)
where
n represents the total number of items,
r represents the number of items being chosen at a time.
Now we have n = 15 and r = 5
Substituting the values,
![15C_5 = \frac{15!}{5!(15- 5)!}](https://tex.z-dn.net/?f=15C_5%20%3D%20%5Cfrac%7B15%21%7D%7B5%21%2815-%205%29%21%7D)
