This video is the third in the series looking at Probability as part of the Year 11 Mathematical Methods (Units 1 and 2) courses here in Australia (but valid throughout the world!). Building on the knowledge from the previous two videos I now look at multi-stage experiments. What happens when I toss a coin twice, three times, four times etc. How to list the outcomes. What is the sample space? How can I work out probabilities? I look at tree diagrams and space space diagrams (for two step experiments). There are a number of worked examples and everything is explained in a clear to understand way. There is also some humour too!

This maths video has been created for courses which are delivered in Australia but, as Maths is a constant, it is equally helpful for students in the USA, UK and other countries who are looking for good maths videos for both high school and middle school.
