Explore what probability means and why it's useful. Probability is simply how likely something is to happen. Whenever we’re unsure about the outcome of an event, we can talk about the probabilities …

If you're curious about the mathematical ins and outs of probability, you've come to the right unit! Here, we'll take a deep dive into the many ways we can calculate the likelihood of different outcomes.

Go deeper with your understanding of probability as you learn about theoretical, experimental, and compound probability, and investigate permutations, combinations, and more!

We give you an introduction to probability through the example of flipping a quarter and rolling a die.

This introduction to probability and statistics explores probability models, sample spaces, compound events, random samples, and a whole lot more.

In this article, we’ll review some probability basics, including how to calculate the probability of two independent events both occurring (event X and event Y) or the probability of either of two mutually …

To find the probability of a certain event, you divide the total number of values that would fulfill that event by the total number of all possible events. Probability can be written as a decimal, a fraction, or a …
