What's G and N?
The local sports team has \(N\) players and \(G\) uniforms. Of course, players need uniforms; in fact, \(N\) uniforms are currently being worn in today's practice. They are thus dirty, and will be sent to laundry. So the players need to pick new uniforms among the remaining \(G-N\) to be used for tomorrow's practice. How many ways are there to select the \(N\) uniforms to be used for tomorrow's practice? (Note that who wears which uniform doesn't matter, just whether a certain uniform is selected or not.)
