KS3 Probability Test Paper with Mark Scheme
A complete end-of-topic KS3 probability assessment for Years 7–9. 14 exam-style questions (35 marks) graded from easy to hard, with stretch questions and a full plain-English mark scheme. Print-ready A4 PDF, 10 pages.
This KS3 Probability test paper is a complete end-of-topic assessment for Years 7 to 9. 14 questions (35 marks) build gently from easier to harder, finishing with a short stretch section for confident mathematicians.
What's covered
The probability scale and the language of likelihood, then calculating probabilities for counters, dice and spinners, including the probability that something does not happen. Sample-space diagrams for two events, expected frequency over many trials, relative frequency from an experiment, and a tree-diagram question to finish.
What's included
- A cover page with space for name, class and date
- 14 questions worth 35 marks, graded from easier to harder, finishing with a short stretch section
- Ruled working space under every question, because method marks matter
- A complete mark scheme written in plain English — the working is shown for every multi-step answer, so you can mark with confidence even if maths is a distant memory
The mark scheme starts on its own page, so you can print the test without the answers. One print-ready A4 PDF, 10 pages — it prints cleanly on ordinary A4 at home.
