This video from Khan Academy describes the Addition Rule with mutually exclusive events and non-mutually exclusive events.. Below is a link to a webpage that also walks through the Addition Rule in both scenarios, then ends with practice problems.

This video defines and works through a couple examples of mutually exclusive events. When creating a probability distribution, it is important to know the entire sample space and how to calculate the probability of certain events within the sample space. When finding probability its just a matter of knowing all possible outcomes and the specific outcomes you are looking for. Below are videos that introduce probability then explore a couple of examples. |
