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.

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

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

Course: AP®︎/College Statistics > Unit 7 Lesson 3: Conditional probability Conditional probability and independence Conditional probability with Bayes' Theorem Conditional probability using two-way …

The probability of Bob having flipped the fair coin isn't simply 50% after observing the outcome of the flip because this scenario involves conditional probability.

Theoretical probability refers to the likelihood of an event occurring based on mathematical principles and assumptions. It is calculated by dividing the number of favorable outcomes by the total number …

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 …
