Description
This is the next video looking at Probability for the Year 9 course and deals with Using arrays for two-step experiments. Whilst we can list all the outcomes from an experiment in a sample space, it's not the most user friendly way of showing the outcomes. This lesson looks at how we can be more visual in the display of the outcomes when we have two-step experiments. What is a two-step experiment? Well, watch the video and all will be revealed. There are lots of worked examples (provided by Cambridge series of textbooks) and the theory is explained in an easy to understand way.
