Difficulty: Medium
About this MCQ
This Medium Discrete Mathematics MCQ checks one syllabus fact.
The question is: “The following statement describes a specific concept. What is it called? a set of ordered pairs that establishes a connection between elements of two sets.”
The accepted answer is A. Relation. “The following statement describes a specific concept. What is it called? a set of ordered pairs that establishes a connection between elements of two sets.” is answered by Relation (option A). Option B (“Permutation”) does not match the stem; it is a near-miss used to catch incomplete recall of Relation. Option C (“Boolean algebra”) does not match the stem; it is a near-miss used to catch incomplete recall of Relation. Remaining alternatives (Recurrence relation) fall outside the same rule and should be eliminated once Relation is identified. Discrete Mathematics questions of this type reward precise definitions rather than approximate associations. Discrete Mathematics recall of this distinction is a regular item in FPSC, PPSC, NTS, and CSS papers.
- A. Relation ✓
- B. Permutation
Why not B: “Permutation” is not correct. The accepted answer is A. Relation. “The following statement describes a specific concept. What is it called? a set of ordered pairs that establishes a connection between elements of two sets.” is answered by Relatio
- C. Boolean algebra
Why not C: “Boolean algebra” is not correct. The accepted answer is A. Relation. “The following statement describes a specific concept. What is it called? a set of ordered pairs that establishes a connection between elements of two sets.” is answered by Relatio
- D. Recurrence relation
Why not D: “Recurrence relation” is not correct. The accepted answer is A. Relation. “The following statement describes a specific concept. What is it called? a set of ordered pairs that establishes a connection between elements of two sets.” is answered by Relatio
Correct answer
