Probability | 25 Worked Examples | Edexcel GCSE Higher Maths

25 progressive Edexcel GCSE Higher (1MA1) probability questions with full mark-scheme style worked solutions.

What’s inside:
Easy: single-event probability, the sum of probabilities, and relative frequency.
Medium: tree diagrams for two events, with and without replacement, and expected frequency.
Hard: conditional probability, Venn diagrams and set notation, and multi-stage problems with algebraic unknowns.

Every solution builds the tree or diagram, keeps one step per line with an annotation on each, and places B, M and A marks where the mark scheme awards them.

Ideal for: Year 10 and 11 students sitting Edexcel GCSE Higher Mathematics (1MA1), plus tutors and teachers building targeted practice. Print-friendly, hand straight to students.
