About this lesson
This video looks at the Binomial Distribution and how we can use it to find more complex probabilities. Starting with a recap of the last video, I then look at how we can use a simple formula (using combinatorics) to find individual probabilities for discrete random variables. I show how to do this using "by hand" and CAS methods. There are a number of worked examples which help me frame the theory. I also look at one of the more complex examples where you need to find the number of trials needed given an overall probability and a probability of success. These questions seem to appear on VCAA papers quite regularly. This video is part of the Year 11 (VCE Units 1 and 2) Mathematical Methods course.
