Tree diagrams are used to represent all possible outcomes of a given event. The Fundamental Counting Principle is a way to calculate the number of outcomes for two or more events. These two concepts can be combined to work out the probability of an event happening.

Tree Diagrams: A graphical representation of all the possible outcomes of a given event. Fundamental Counting Principle: A mathematical rule which states that if an event has m possible outcomes, and another event has n possible outcomes, then the total number of possible outcomes for both events is m x n. Probability: The measure of how likely an event is to happen, expressed as a fraction, decimal or percentage.

The Fundamental Counting Principle was first used in the 1700s by a Swiss mathematician called Jacob Bernoulli. In mathematics, tree diagrams are also known as decision trees. Probability is used in many areas of science, including weather forecasting.
