Let 1 ≤ m ≤ n be integers. Give a combinatorial proof of the identity n+m Σ (:) ( ".) ( ^_) - (.") ("+"). 2 km) m) k=n-m Hint: Think of the number of ways of choosing a team of n players from given two groups of n people and choosing n-m of these players as team leaders with some additional restriction. You need to figure out what should this "additional restriction" be.
