Conditional probability could describe an event like: Event A is that it is raining outside, and it has a 0.3 (30%) chance of raining today. Event B is that you will need to go outside, and that has a probabilit
In this lesson you will learn the definition of conditional probability, and how it differs from other kinds of probability. You will also learn how to use the formula for calculating conditional probability and see it being used in two examples. After the lesson, you will take a brief quiz...
Conditional probability refers to the chances that some outcome (A) occurs given that another event (B) has already occurred. In probability, this is written as A given B, or as this formula: P(A|B), where the probability of A happening depends on that of B happening. ...
Conditional probability involves finding the probability of an event occurring based on a previous event already taking place. To calculate a conditional probability, we must use the process of dependent events because the first event will affect the outcome of the second event. The difference is ...

The probability that the second counter is black depends on what the colour of the first counter was. Step-by-step guide: Conditional probabilityHow to calculate probability In order to calculate probability: Write out the basic probability Solve the problem, using AND or OR rules as appropriate...
What is Joint Probability? Joint probability is the likelihood that two or more events will coincide. Knowing how to calculate them allows you to solve problems such as the following. What is the probability of: Getting two heads in two coin tosses?
Lecture 5Conditional Probability, Bayes Theorem and independent Events with ExamplesDr Kashmar
The marginal probability of an event is the probability distribution that describes that single event only. The conditional probability, on the other hand, is a distribution that represents the likelihood of an event to occur given a particular outcome of another event. How do you find the margi...
As you can see, Bayes’ Theorem can help you calculate the probability of an event occurring, given that another event has already occurred. Summary Bayes’ Theorem is a powerful tool that can be used to solve problems in many different fields. This formula can be very helpful to lenders....
