1. Construct the truth table for (p q) (¬p q)
p | q | ¬p | p q | ¬p q | (p q) (¬p q) |
2. Populate the truth table and see whether this statement is correct: p q ≡ ¬q ¬q
p | q | p q | ¬ p | ¬q | ¬q ¬q |
3. Populate the provided truth table for the statement demonstrating De Morgan’s Law: ¬(p q) ↔ ¬p V ¬q
p | q | ||||||
4. Use truth tables to show whether the following propositions are equivalent:
Proposition 1: p ∧ (q ∧ r)
Proposition 2: (q ∨ q) ∧ (q ∨ r)
p | q | r | |||||
5. For this logic circuit provide:
a. the propositional logic formula
b. the truth table.
¬ (A ∨ B)
AND
