Foundational rules of probability, independence, and conditional events.
This chapter introduces nonparametric statistics, which are useful when data does not meet the assumptions of a normal distribution. It covers the Chi-square goodness-of-fit test and the Chi-square test for independence in a contingency table.

Set notations, counting rules (permutations/combinations), and conditional probability.
Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1 that represents the chance or probability of an event happening.
These describe how "spread out" the data is.
