The number of combinations of n dissimilar things taken r at a time will be nC r. Now if we take out a group of r things, we are left with a group of (n-r) things. Hence the number of combinations of n things taken r at a time is equal to the number of combinations of n things taken (n-r) at a time. ∴ nC r= nC n−r.
