Can anyone derive the following: 'n' identical things are distributed among 'r' persons. The formula for this is C(n-r+1,r-1). How do you derive this ? Thanks

You start small, derive a conjecture, attempt to prove your conjecture, expand your small start, improve your theory, and on and on and on... It's called INVESTIGATION!
