This video explains how to work with tree diagrams for probability. We explain how to use them to calculate probabilities for a combination of outcomes for more than one event and how to draw a tree diagram for a probability question. This is an updated, 4K version of our previous video. Practice questions and answers are at the end of the video. • Skip to: • 00:00 Introduction • 00:24 what is a tree diagram? • 01:31 All branches from a single point should add up to 1 • 02:07 Multiply along branches to obtain probability for a combination of outcomes. • 03:26 Adding up probabilities for more than one set of outcomes. • 04:15 Tree diagrams practice question and answers • • • Educational maths help videos to learn mathematics for school, exams or just general life.
