The most direct links, roughly in order of how often they actually come up:
Apply probability concepts (91585): the same conditional-probability habit Computing P(A | B) the right way round and comparing the result against a claim is the same evaluative habit that standard drills with tree diagrams and two-way tables — here you compute it from a triangular or normal model instead. Evaluate statistically based reports (91584): the same claim-vs-calculated-value shape Testing a claim against a calculated value and stating an explicit verdict is the same evaluation shape used across all three Level 3 Statistics externals — only the source of the numbers changes. Physics: Modern Physics (91525): radioactive decay is a real Poisson process Radioactive decay counts are the textbook Poisson process: random events at a constant average rate. A Geiger counter's irregular clicking IS the Poisson distribution, and it shows why the conditions matter — decays are independent, and the rate is constant only while the half-life is long compared with your counting window. ✓
