What is the name for a table that shows all possible truth values of a logical expression based on its input variables?
Difficulty: Easy
About this MCQ
This Easy Discrete Mathematics MCQ checks one syllabus fact.
The question is: “What is the name for a table that shows all possible truth values of a logical expression based on its input variables?”
The accepted answer is A. Truth table. Truth table is the fact required by “What is the name for a table that shows all possible truth values of a logical expression based on its input variables” (option A). Option B (“Mathematical induction”) does not match the stem; it is a near-miss used to catch incomplete recall of Truth table. Option C (“Graph theory”) does not match the stem; it is a near-miss used to catch incomplete recall of Truth table. Remaining alternatives (Proposition) fall outside the same rule and should be eliminated once Truth table 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.
