Tree Diagram Example Resource (Free Download)

Suitable for Year groups: 10, 11

Tree Diagram Example resource description

In this example the probability of rolling a 3 on fair six sided dice is considered and displayed on a probability tree diagram. We also demonstrate how to use the tree diagram to calculate the probabilities of rolling two 3s or one 3 after two dice rolls.

Tree Diagram Example

This resource provides a worked example using a tree diagram to solve a probability problem involving multiple events.


Why are tree diagrams important?

Tree diagrams help us:

  • Visualise probabilities: Clearly show possible outcomes and their chances.
  • Analyse multi-step events: Understand probabilities over several stages.
  • Calculate complex probabilities: Solve problems in a structured way.

How can this resource help?

This resource offers a step-by-step solution:

  • Problem setup: Presents a clear probability problem.
  • Tree diagram construction: Shows how to draw the diagram.
  • Calculations: Demonstrates finding probabilities for each branch.
  • Solution: Provide the final answer with an explanation.
  • Free PDF download: Offers an easily accessible reference tool.

Benefits for learners:

  • Improves understanding of using tree diagrams.
  • Provides a model for solving similar problems.
  • Supports problem-solving and organisation skills in probability.

This resource is perfect for teachers introducing or reviewing tree diagrams. It's also valuable for students needing extra practice or for parents helping with probability homework.
