Calculate theoretical probability in Year 9 Maths
Start here
Focus on probability tree diagrams. Open support for “Calculate Probability from Tree Diagrams”, then explain the idea in your own words.
Year 9 learners practise probability tree diagrams.
The activities include Calculate Probability from Tree Diagrams, Calculate Probability of a Complementary Event from Tree Diagrams, Complete Probability Tree Diagrams for Without Replacement Scenarios, and related practice. The checked support below includes video, worksheet, teaching, lesson. Open a resource in its provider's website and choose the format that best helps the learner explain the idea independently.
