    Does anyone know what truth tables would be for these formula?

    1. P → ( P & P)

    2. P & ¬ P

    3. P ˅ ¬ P

    4. P → ( Q → P)

    5. ( P & Q) ↔ (Q & P)

    6. (P ˅ Q) ↔ ¬ Q

    7. (P → Q) → (¬ Q → ¬P)

    8. ¬( P ˅ Q) ↔ (¬P &¬Q)

    OK thanks. Do you want the truth table with T (True) and F (False)?
