Key Stages: 3 and 4 ★
Can you use the interactivity to identify which combinations of spinners have produced the bar charts shown?
This problem provides a motivation to use sample space diagrams. The interactivity offers an ideal context in which to observe the "messy" randomness of results after a small number of experiments, and the predictability of results after a large number of trials.
The problem also offers a good starting point for considering different probability distributions and their features.
This resource has comprehensive teachers' notes and resources, linked from the problem page. This includes possible approaches and key questions, as well as possible support and extensions.
