The formula of combination is
![nCr= \frac{n!}{(n-r)!r!}](https://tex.z-dn.net/?f=nCr%3D%20%5Cfrac%7Bn%21%7D%7B%28n-r%29%21r%21%7D%20)
We have
![n=14](https://tex.z-dn.net/?f=n%3D14)
and
![r=10](https://tex.z-dn.net/?f=r%3D10)
![14C10= \frac{14!}{(14-10)!10!} = 1001](https://tex.z-dn.net/?f=14C10%3D%20%5Cfrac%7B14%21%7D%7B%2814-10%29%2110%21%7D%20%3D%201001)
Hence, there are 1001 ways of arranging 10 records from 14 records
