Question 1 · 1 mark · Difficulty 1/3

A teacher in Port of Spain asked students to list all the prime numbers less than 10. Which type of set does this collection represent?

  1. Finite set
  2. Infinite set
  3. Empty set
  4. Universal set
Show answer & explanation
✓ Answer: AFinite set
Award 1 mark for identifying that the set {2, 3, 5, 7} contains a countable number of elements (exactly 4). B is incorrect — an infinite set has unlimited elements. C is incorrect — the set contains elements. D is incorrect — a universal set contains all elements under consideration.
Question 2 · 1 mark · Difficulty 1/3

The set of all students in a mathematics class at a secondary school in Kingston is used as the reference for a survey about study habits. This set is called the:

  1. Empty set
  2. Subset
  3. Universal set
  4. Infinite set
Show answer & explanation
✓ Answer: CUniversal set
Award 1 mark for recognising that the universal set contains all elements being considered in a particular problem. A is incorrect — the class has students. B is incorrect — a subset is part of another set. D is incorrect — the number of students is countable.

CXC CSEC Mathematics: Sets: Types of sets — finite, infinite, universal set, empty set, subsets and equal sets FAQ

How many CXC CSEC Mathematics questions on Sets: Types of sets — finite, infinite, universal set, empty set, subsets and equal sets are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Sets: Types of sets — finite, infinite, universal set, empty set, subsets and equal sets for CXC CSEC Mathematics, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real CXC paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for CXC CSEC students preparing for Mathematics?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Sets: Types of sets — finite, infinite, universal set, empty set, subsets and equal sets practice with other Mathematics topics or even switch to a totally different CXC subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Sets: Types of sets — finite, infinite, universal set, empty set, subsets and equal sets questions aligned to the official CXC CSEC Mathematics syllabus?
Every question is written against the published CXC CSEC Mathematics specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CXC paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from CXC.
How is Sets: Types of sets — finite, infinite, universal set, empty set, subsets and equal sets typically tested on CXC CSEC Mathematics papers?
Sets: Types of sets — finite, infinite, universal set, empty set, subsets and equal sets appears across multiple question types on real CXC CSEC Mathematics papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
