Normal Distribution | 25 Worked Examples | Edexcel A-Level Maths

25 progressive Edexcel A-Level (9MA0) normal distribution questions (Statistics, Paper 3) with full mark-scheme style worked solutions.

What’s inside:
Easy: finding probabilities from a normal distribution and standardising values using z.
Medium: the inverse normal (finding a value from a given probability), and finding an unknown mean or standard deviation.
Hard: the normal approximation to the binomial, and harder problems with two unknowns to find.

Every solution shows every step, with M1 (method), A1 (accuracy) and B1 (independent) marks annotated at exactly the point each would be awarded. Typeset in LaTeX for clean mathematical notation.

Ideal for: Year 13 students sitting Edexcel A-Level Mathematics (9MA0) Paper 3 Statistics, plus tutors and teachers building targeted practice. Print-friendly, hand straight to students.
