The Fundamental Counting Principle says: If there are m ways to one thing and n ways to do another, then there are m*n ways to do both. Of course this idea can be extended to more than two events also. (Time stamp below)
In this video we look at what the Counting Principle is and see how to apply it in different situations. Examples include independent events (events whose outcomes do not affect each other) and dependent events (events for which the outcome of one affects the outcome of the other.)
