  1. What do you need to do to find the number of variations if order doesn’t matter?
  2. How is this process the same/different from the number of the number of variations when order DOES matter?

* As you are testing possibilities, use different numbers of “choices” and choose different amounts at a time.  Otherwise you won’t get a full picture.  (For example, try 5P2 and 5P3 but also 4P2 and 4P3).  You can use tree diagrams and a table to keep track of your experiments.  Keep your numbers small to avoid having a “stabby” feeling. :)
