In this permutation and combination math tutorial, we will learn how to find the number of possible arrangements in a set of objects. So, if you need help with your algebra or geometry homework, watch this.
An arrangement of a set of objects in a certain order is called a PERMUTATION. To find the number of permutations of a certain set, use the factorial notation.
A COMBINATION is a selection of items in which the order of the elements is not considered.
