COUNTING AND ARRANGEMENTS

This unit is about various counting techniques to calculate probability and the number of outcomes. The Fundamental Counting Principal is the underlying principle for determining the number of possible outcomes.  There are two types of counting arrangements: permutations and combinations.  A permutation is an arrangement of objects in which the order of the arrangement is important to the number of outcomes.  A combination is an arrangement of objects where order is not taken into account and results in fewer outcomes than permutations.
