So you are interested in learning about Unions and Intersections with Venn Diagrams? Well, you've come to the right place. I have loved creating this video! I open by explaining some of the key terms we use in probability. I then use these to explain not only what a Venn Diagram is for, but how to create them for both mutually exclusive data and data which has an overlap. I discuss how we can find the union and intersection of the events and what it means when numbers are written outside of the two (or more!) circles. Probability tables and Karnaugh Maps are shown by using examples and then I dive into some awesome examples showing how we can use Venn Diagrams and Karnaugh Maps to solve problems. So much fun had in this one video! I hope you enjoy it.
If you think I'm about to teach you to count, I can promise you that I'm well past doing that with this video. This Addition Rule deals very much with what to do with Year 10 probability. And who isn't excited by a little bit of addition rule! I open with a recap of the work we have done with Venn Diagrams and how they can use used to find numbers and probabilities. I then take a look at how we might have lied to you in Year 7 ... or at least bent the truth a bit with the questions we have given you. Remember: When we see the word AND we times and OR we add? Well, I tell you why that isn't actually true. I show you how the Addition Rule comes to be and what happens to it when we have Mutually Exclusive Data. A number of examples are then looked at and I end the video with a 40-second recap of all the work. Phew! I'm exhausted just typing this ... much less watching the video. Thanks for taking the time in reading this and watching the video!
So you're interested in conditional probability, are you! Well, you've come to the right place. This video will explain to you the ideas behind conditional probability by first looking at a Venn Diagram and explaining what it means by the "Given That" wording and notation. We look at how to read the Venn Diagram (and later a two-way table) to ensure that you know how to visually find the conditional probability of two events. Isn't there a formula? Of course! So, I take the time to look at the two forms of the conditional probability formula before doing some examples showing how it works. So much fun in just the one video!
This video looks at how to draw and use tree diagrams to find sample spaces and probabilities of events happening. A number of worked examples are provided and a great explanation of how a tree diagram related and used conditional probability. Thanks for watching! I hope you enjoy
