In the Probability Fundamentals for R Users course, we covered the fundamentals of probability and learned about:

- Theoretical and empirical probabilities
- Probability rules (the addition rule and the multiplication rule)
- Counting techniques (the rule of product, permutations, and combinations)

In this course, we'll build on what we've learned and develop new techniques that will enable us to better estimate probabilities. Our focus for the entire course will be on learning how to calculate probabilities based on certain **conditions** — hence the name **conditional probability**.

By the end of this course, you'll be able to:
