This is another video in the series looking at Probability for the Year 9 course. Barry has outdone himself with the notation we can use in Probability and this video seeks to break down all the confusion and have you using Set Notation like a Mathematical genius! I explain what intersection, union, element of, empty set, subsets and contained within mean with lots of examples. The lesson is aligned with the Cambridge series of textbooks and, with permission, I use their examples to explain how to master the concepts. This lesson is delivered with my own unique style of humour.
