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 of certain outcomes—how likely they are. The analysis of …

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.

And it makes much more sense to talk about the probability of a random variable equaling a value, or the probability that it is less than or greater than something, or the probability that it has some property.

The probability of getting "heads," given that it's a Tuesday, is still 1 / 2 . So the result of a coin flip and the day being Tuesday are independent events; knowing it was a Tuesday didn't change the …

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

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.

While the probability of a specific point in a continuous distribution being exactly equal to a particular value is indeed 0, the mode is still a meaningful concept because it represents the most frequently …

And so, if you were to say theoretically, what is the probability, if you stuck your hand in and you're not looking, what is the probability of picking a magenta?

The equation P (A and B) = P (A ∣ B) × P (B) might seem confusing at first, but it's essentially saying that the probability of both events A and B happening is the probability of event A happening given that …

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