Understand probability outcomes in Year 9 Maths
Start here
Focus on conditional probability and independent events. Open support for “Calculate Conditional Probability”, then explain the idea in your own words.
Year 9 learners practise conditional probability and independent events.
The activities include Calculate Conditional Probability, Calculate Probabilities of Exhaustive Sets of Mutually Exclusive Events, Calculate Probability, 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.
