Probability Tree Diagrams Explained
This animation builds a probability tree diagram step by step using a simple two-event example, such as drawing colored balls from a bag with and without replacement. It shows how to label branches with outcomes and probabilities, multiply along branches to find combined event probabilities, and add across branches for total probability. Designed for O Level and IGCSE Maths students, it clarifies how tree diagrams organize dependent and independent events for clear, accurate calculations.
