Probability tells us how often some event will happen after many repeated trials. You've experienced probability when you've flipped a coin, rolled some dice, or looked at a weather forecast.

Statistics and probability Course: Statistics and probability > Unit 7 Lesson 1: Basic theoretical probability Intro to theoretical probability Probability: the basics

Learn statistics and probability—everything you'd want to know about descriptive and inferential statistics.

In this unit, you'll learn the basics of probability, like counting and combining things to find the chance of something happening. You'll explore rules for independent and dependent events, and dive into …

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.

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.

Learn high school statistics—scatterplots, two-way tables, normal distributions, binomial probability, and more.

Practice finding probabilities of events, such as rolling dice, drawing marbles out of a bag, and spinning spinners.

In order to find the probability of picking a yellow marble from a bag, we have to first determine the number of possible outcomes, and then how many of them meet our constraints.
