This chapter is a deep dive introduction into a serious study of probability and counting the number of ways things in this world can happen! Your rad road starts with an introduction to theoretical probability. From there you will learn about the counting principle and why it works (so very cool!!!). A short hop from here you will learn about compound events – A.K.A. independent and dependent events. Your studies continue with permutations, combinations, and a new math operation – factorials!! The chapter ends with explorations into experimental probability and using probability to make predictions. The world around us is full of seemingly countless possibilities and chances…learn how to calculate some of these scenarios!
