About this course
In this unit, we will cover fundamental rules of probability including how to describe random events. We will cover topics such as set theory, conditional probability, joint probability, Bayes rule, probability distributions, and sampling distributions. These concepts are important in order to understand the likelihood of events, fit machine learning models, and perform hypothesis tests.

Frequently asked questions about Probability
Probability is a type of math that helps us determine the chances of something happening. For example: When you flip a coin, there’s a 50/50 chance of it landing on either heads or tails. That’s essentially what probability is — calculating the likelihood of a certain outcome or event.
