You've experienced probability when you've flipped a coin, rolled some dice, or looked at a weather forecast. Go deeper with your understanding of probability as you learn about …

Here, we'll take a deep dive into the many ways we can calculate the likelihood of different outcomes. From using simulations to the addition and multiplication rules, we'll build a solid …

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

A random variable is some outcome from a chance process, like how many heads will occur in a series of 20 flips, or how many seconds it took someone to read this sentence. Calculate …
