Difficulty: Easy
About this MCQ
This Easy Discrete Mathematics MCQ checks one syllabus fact.
The question is: “The concept in which a set operation that combines all elements from two or more sets into a single set without duplication is best known as which of these terms?”
The accepted answer is C. Union (set operation). The concept in which a set operation that combines all elements from two or more sets into a single set without duplication is best known as which of these terms is answered by Union set operation option C Option A Contrapositive does not match the stem it is a near-miss used to catch incomplete recall of Union set operation Option B Intersection set operation does not match the stem it is a near-miss used to catch incomplete recall of Union set operation Remaining alternatives Equivalence relation fall outside the same rule and should be eliminated once Union set operation is identified Discrete Mathematics questions of this type reward precise definitions rather than approximate associations Discrete Mathematics recall of this distinction.
- A. Contrapositive
Why not A: “Contrapositive” is not correct. The accepted answer is C. Union (set operation). The concept in which a set operation that combines all elements from two or more sets into a single set without duplication is best known as which of these terms is answered by Uni
- B. Intersection (set operation)
Why not B: “Intersection (set operation)” is not correct. The accepted answer is C. Union (set operation). The concept in which a set operation that combines all elements from two or more sets into a single set without duplication is best known as which of these terms is answered by Uni
- C. Union (set operation) ✓
- D. Equivalence relation
Why not D: “Equivalence relation” is not correct. The accepted answer is C. Union (set operation). The concept in which a set operation that combines all elements from two or more sets into a single set without duplication is best known as which of these terms is answered by Uni
