• ### Unit 2: Counting Theory

"How many elements do we expect to find within a given set?" This is a simple question, but hard to answer correctly without guessing. Counting theory (also known as combinatorics) lets us do that through several different approaches that depend on the circumstances of the given problem. These approaches are not difficult, but you have to know when to use each one, and which circumstances each approach applies to. In this unit, we will carefully walk through these considerations.

Completing this unit should take you approximately 5 hours.
