Understand Probability Outcomes

Year 8 learners practise probability of combined events.

The activities include Calculate Outcomes from Combined Events, Calculate the Number of Different Combinations of Ice Creams, Calculate the Number of Different Combinations of Outfits, and related practice. The checked support below includes video, teaching, worksheet, lesson. Open a resource in its provider's website and choose the format that best helps the learner explain the idea independently.
