infoWhy this? Discrete random variables provide a precise framework for modelling countable outcomes and describing their expected values and variability. The Poisson distribution models counts of events occurring independently at a constant mean rate over time or space, helping us connect probability calculations with real situations and evaluate modelling assumptions.

scheduleWhy now? GCSE probability and algebra provide an accessible starting point without requiring advanced pure mathematics. Establishing discrete probability models first gives us the foundations for the hypothesis testing that follows and for the wider range of distributions introduced in Year 13.
