The formula to find how many different ways are there to choose a subgroup of r things from a group of n things is
![\frac{n!}{(n-r)!}](https://tex.z-dn.net/?f=%5Cfrac%7Bn%21%7D%7B%28n-r%29%21%7D)
Here, you have 7 trophies and you want to choose 4 of them, so you have
![\frac{7!}{(7-4)!}\text{ = }\frac{5040}{6}=840](https://tex.z-dn.net/?f=%5Cfrac%7B7%21%7D%7B%287-4%29%21%7D%5Ctext%7B%20%3D%20%7D%5Cfrac%7B5040%7D%7B6%7D%3D840)
So there are 840 ways to choose your 4 trophies out of the 7 you have.
