Explanation The given identity is ∑ k = 0 n ( n k ) ( m − n n − k ) = ( m n ) . R.H.S: Here, ( m n ) is the number of arrangement of n object from m distinct object. For example, n balls are drawn from a box, which is contained m balls at the beginning. The balls are named from 1 to m and placing in a smaller box. L.H.S: Here, ( n k ) is the number of ways to select k objects from n elements. Also, ( m − n n − k ) is the number of ways to select n − k objects from m − n elements. By using the above example, k balls are drawn from a box and selecting balls are named with n ≤ m . After selecting a k balls, then select the extra n − k balls and the selected balls are named with numbers greater than n
