# Probability

Enter the world of probability and start learning the basics to solve problems, perform operations between events and apply Laplace's rule. At a more advanced level discover conditional probability, the total probability theorem and Bayes' formula. To get there it is always a good idea to learn to work with contingency tables and tree diagrams.
