A tree diagram is a way of representing a sequence of events and are particularly useful in probability since they record all possible outcomes in a clear and uncomplicated manner. In this class, students will learn how to construct tree diagrams and calculate the probability of different events. This class is aimed at students in Years 9 - 11 and is important to review as it can appear in both the Higher and foundation paper at GCSE level.
