Lesson 6 in our new Tom Rocks Maths Appeal YouTube series is OUT NOW!

Team Maths Appeal (me and Bobby Seagull) have joined forces with the University of Oxford mathematician, Dr Tom Crawford (aka Tom Rocks Maths) to explore and teach topics from the GCSE Maths syllabus. We aim to show the world that maths is accessible to everyone!

In this episode you will learn how to use probability tree diagrams to calculate the probability of an event happening. Bobby introduces the topic, I share an interactive tool on GeoGebra – go to https://www.geogebra.org/m/EEwVfExN to join in at home – and Tom applies what we’ve learned to a fictional FA Cup quarter final draw. Direct links to each part below.
