Imagine you are rearranging 6 books on a shelf.   There are many different ways to arrange those books.  The fundamental counting principle can be used to determine how many books can be placed in each position.  As each book is used, there are fewer books to put into the next slot.  This ordered arrangement is also called a Permutation and there are different ways to figure out how many permutations for a given group are available.

Things you should be able to do after today:

  • Understand and solve problems involving factorial notation
  • determine the number of permutations of distinct (different) objects when all of the objects are used or only some of the objects are used
