About this probability game
This free probability game gives GCSE-level students practice working out the probability of single events, combined independent events, and probabilities that must sum to 1. Choose which question types to include, set your question count and time limit, then work through as many as you can, giving each answer as a fraction in its simplest form. It's a solid way to build fluency with probability notation and reasoning ahead of exams.
