Let be . Show that but that neither nor (Note: this question is using Propositional logic) My current attempt is this: 1. Given 2. Assume 3. Assume 4. Using "OR introduction" 5. Contradiction in lines 2 and 4 6. Derive using Reductio Ad Absurdum 7. Assume 8. Using "OR introduction" 9. Contradiction in lines 2 and 8 10. Derive using Reductio Ad Absurdum 11. Using "AND introduction"
