Probability - Experimental and Theoretical
Key Stage: 3 ★
You throw two discs, and win if they show the same colour. Approximately how often would you win if you threw the discs 100 times? What if there were more discs?
This problem offers an opportunity to explore and discuss two types of probability: experimental and theoretical. The simulation generates lots of experimental data quickly, freeing time to focus on predictions, analysis and justifications.
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.

An excellent probability tool which is especially useful because it's possible to use this with pupils of all ages. The visual aid is helpful for low ability pupils and the numerical data to accompany it on the right hand side provides plenty of scope for discussion and interpretation.
