PROBABILITY: FUNDAMENTAL COUNTING PRINCIPLE, PERMUTATIONS, COMBINATIONS

In this unit, you will begin by learning the fundamental counting principle and applying it to probabilities. You will then explore permutations, which are used when the outcomes of the event(s) depend on order, and combinations, which are used when order is not important.
