About Lesson
This video recaps all the exciting terminology which is needed to be able to answer (pretty much) every probability question on the planet. Well, maybe not every one! But a lot. I do all I can to make it amusing and real world. That's pretty hard with this rather dry subject!
The language of probability is really important. This video looks at the areas shown in the key points below.
