7. Let 1< m <n be integers. Give a combinatorial proof of the identity
k
n
'n + m
=
- m
п — т.
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.
