Propositional Logic — AI Technical Interview Questions & Answers

Propositional Logic

Propositional Logic

  • Propositional logic: atomic sentences that are true or false, joined by ∧ ∨ ¬ → ↔. No “for all students”. P = “it rains”. Q = “ground wet”. P → Q. Truth tables decide entailment. Limited, but easy to implement.
  • You cannot say “every pit has a breeze” without repeating a sentence per square. That limit is why FOL exists. MCQ: implication is not “and”.
  • Output: idea / do / check for Propositional Logic. Fill those three in the viva.

Technical Interview Tip: One implication example + why FOL is richer.

Code Examples for Propositional Logic

Example

# Propositional Logic
print("idea :", "Propositional Logic")
print("do   : one tiny example on paper")
print("check: one failure case")

Output: idea / do / check for Propositional Logic. Fill those three in the viva.

How to Explain Propositional Logic to an Interviewer

Explain Propositional Logic as if you are teaching a junior — definition, then one example.

True/false sentences + connectives. No quantifiers.

What does the example print, and what does that prove?
