Chapter 2 – Probability
This lesson, Binomial Probabilities – Part I is the first of two lessons calculating probabilities of repeated trials with outcomes that have only two possibilities, such as flipping a coin. This lesson deals with the ‘fair’ case where the probabilities are each 50%. A future lesson, Binomial Probabilities – Part II expands this to arbitrary probabilities. The connection to Pascal’s Triangle is important, and it is assumed that students have familiarity with Pascal’s Triangle. The recursion for Pascal’s Triangle, and its connection to counting techniques is embedded in the lesson and is of fundamental importance to understanding this concept.
