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 …
Compound probability of independent events - Khan Academy
Learn how to calculate probabilities of coin flips using two methods: listing all possible outcomes or multiplying independent events. Understand what independent events are and how to avoid …
Probability | Lesson (article) | Lessons | Khan Academy
How is the probability of an event calculated? An event could be the outcome of any random process such as the toss of a fair coin, the roll of a fair number cube, or the random selection …
Probability of the event 'not A' (video) | Khan Academy
In this video, we'll learn how to find the probability of a complement of an event. We first take a concrete example and get an intuition of how probabilities add up to 1.
Probability models example: frozen yogurt - Khan Academy
Definition of Theoretical Probability. It is the likeliness of an event happening based on all the possible outcomes. The ratio for the probability of an event 'P' occurring is P (event) = number …
Probability of an event (practice) | Khan Academy
A bag contains 3 red discs, 4 blue discs and 2 yellow discs. Rahul pulls out a disc at random. Find the probability that the disc is blue.

Finding probability of an event given another - Khan Academy
This video focuses on calculating conditional probabilities P (E|F) by first defining the sample space and the specific events E and F. We'll work through examples involving tossing a coin …
Probabilities involving "at least one" success - Khan Academy
If you're asked to find the probability of an event happening (e.g., at least one patient rejects the implant), you can use the complement rule by subtracting the probability of the event not …
