When given a of objects and we would to find the possible different arrangements or selectionswe may use permutations or combinations. Permutations deal with the arrangement of objects. The order of the objects is important. The of different arrangements of r objects from n distinct object is.

Combinations deal with the selection of objects. The order of the objects is not important. The of different selections of r objects from n distinct object is. Notice that it is also used as the binomial coefficients in Binomial Expansion and Binomial Series. We have 3 letters, A, B and C and we would like to find the permutations and combinations of 2 letters from the 3 letters.
