Unit 2 focuses on the mathematical study of randomness and uniqueness, providing tools to calculate the likelihood of specific events through counting methods and fundamental rules. The notes introduce factorials for recursive multiplication and distinguish between permutations and combinations. The notes also detail various rule sets for complex probabilities, such as the General Addition Rule, Multiplication Rule, Conditional probabilities, and Disjoint events.

These notes give an overview of introductory statistics, focusing on the methods used to describe and visualize data sets. The notes define key terminology such as measures of center and spread while providing the specific mathematical formulas for calculating mean, standard deviation, and variance. Viarious graphical representations, including histograms, dot plots, and stem-and-leaf displays, to identify patterns like clusters or gaps. Additionally, the text explains how to classify differ...

Key terms and formulas for statistics, different distribution types and detailed explanations and use cases, different types of graphs commonly seen in statistics, how to find center and spread, explains 5 number summary, introduction and base uses for the normal distribution.
