The difference between the two is whether or not order is important. If you have a problem where you can repeat objects, then you must use the Fundamental Counting Principle, you can't use Permutations or Combinations
How is permutation different from other counting techniques?
ANSWER:
The Fundamental Counting Principle works similarly for more than two events - multiply the number of outcomes in each event together to find the total number of outcomes. Technique #2: Permutations: Use this when you are counting the number of ways to choose and arrange a given number of objects from a set of objects.
