In these lessons, we will learn about permutations how to solve permutation with and without repetitions.
Introduction To Permutations
Calculating Permutations (arrangements)
Counting the number of way to arrange n distinct objects.
If you are not familiar with the n! (n factorial notation) then have a look the factorial lessons.
Why Is Order Important In Permutations
Students learn that a permutation is an arrangement of objects in which the order is important. For example, the permutation AB is different than the permutation BA. Students are then asked to solve word problems involving permutations.
Two examples of counting using permutations and the basic counting principle.
