Statistics and Probability

Overview

The beginning of this chapter is an introduction to the field of statistics, including statistical measures and various diagrams of data. The Fundamental Principle of Counting, permutations, and combinations are used to determine the number of ways an event can happen. The chapter ends with two sections on calculating probability and mutually exclusive, independent, and dependent events.
