9th Grade Two Sets Quizzes, Questions & Answers

9th Grade

Top Trending Two Sets Quizzes

Are you ready to make sense of how two sets overlap? In this quiz, you’ll explore how the inclusion–exclusion principle helps you calculate unions and intersections with confidence. You’ll practice...

Questions: 20 | Attempts: 11 | Last updated: Dec 17, 2025

Sample Question 1
Which formulas correctly represent the size of the union of two finite sets A and B?

|A ∪ B| = |A| + |B|

|A ∪ B| = |A| + |B| − |A ∩ B|

|A ∪ B| = |A| − |B| + |A ∩ B|

|A ∪ B| = |A ∩ B|

Sample Question 2
In which situations would double-counting occur if we added |A| + |B| directly?

Counting students who like both music and drama

Counting only those who like exactly one activity

Adding disjoint categories

Including overlapping members twice

Sample Question 3
Which pair of sets is disjoint?

Even numbers and Odd numbers

Multiples of 2 and Multiples of 4

Prime numbers and Composite numbers (≥2)

Even numbers and Multiples of 3

Recent Two Sets Quizzes

Inclusionâ€“Exclusion for Two Sets (Applied & Algebraic Focus)

Can you use inclusion–exclusion beyond basic set diagrams? In this quiz, you’ll apply the idea to algebraic expressions and more complex counting setups. You’ll begin with straightforward numerical cases and...

Questions: 20 | Attempts: 11 | Last updated: Dec 17, 2025

Sample Question
In a survey, |M| = 60 like Music, |A| = 45 like Art, |M ∩ A| = 25. Which statements are true?

|M ∪ A| = 105

|M ∪ A| = 80

Exactly one = 55

M and A are disjoint
