Core finding
This Continuous random variables syllabus point appears in 11 WST02 papers across 2015–2026, contributing 14 topic questions and 27 marks. The most recent appearance is WST02/01 January 2026. That equals 4.4% of the 316 topic questions and 3.0% of the 912 marks tagged to Continuous random variables. Only parts tagged to this subtopic are counted, so a four-part question can contribute one item and one part's marks. The table lists every matching question, its tagged parts and marks, with a link back to the paper page. Sessions are newest first, so the statement can be traced back through the full paper history.
Topic questions by session
Newest sessions first. Parts and marks count only the parts tagged to this subtopic; “x of y parts” shows how much of the question is tagged elsewhere.

Topic question rules and edge cases
- How many topic questions cover this syllabus point?
- 13 question stems cover this subtopic across 11 papers, but only 14 tagged parts and 27 marks belong to it. Other parts of the same questions are assessed under different statements and are excluded from this page.
- Which papers include this subtopic?
- The table lists every matching session from 2015–2026. Each row links to the question anchor on the paper page, where the full paper context and practice entry point are available.
- Why can one question appear under several subtopics?
- The parts of one question can assess different syllabus statements. Each part is counted under its own subtopics, so the same question stem can appear on several subtopic pages while each page lists only the parts and marks tagged to that statement.
- Can I practise these questions with AI marking?
- Yes. Open a paper from the table and use the Interactive Practice Hub entry point. The page itself is static HTML so search engines and retrieval agents can read the full question list without executing JavaScript.
