Logical Classification
1. **State the problem:** Determine whether the logical formula $$((p \to n2) \lor (p \to q))$$ is a tautology, contingency, or contradiction.
2. **Recall definitions:**
- A **tautology** is a formula that is true in every possible interpretation.
- A **contradiction** (absurdity) is false in every interpretation.
- A **contingency** is true in some interpretations and false in others.
3. **Analyze the formula:**
The formula is $$((p \to n2) \lor (p \to q))$$.
4. **Note:** The symbol \(n2\) is unusual in propositional logic; assuming it is a propositional variable (like \(p\) or \(q\)).
5. **Recall implication equivalence:**
$$p \to r \equiv \neg p \lor r$$
6. **Rewrite each implication:**
$$p \to n2 \equiv \neg p \lor n2$$
$$p \to q \equiv \neg p \lor q$$
7. **Rewrite the whole formula:**
$$((\neg p \lor n2) \lor (\neg p \lor q))$$
8. **Simplify using associativity and idempotency:**
$$\neg p \lor n2 \lor q$$
9. **Interpretation:**
The formula is true if \(\neg p\) is true, or \(n2\) is true, or \(q\) is true.
10. **Check if formula is always true:**
- If \(p\) is true, then formula depends on \(n2 \lor q\).
- If both \(n2\) and \(q\) are false, formula is false.
11. **Conclusion:**
The formula is not always true (not a tautology).
It is not always false (not a contradiction).
Therefore, it is a **contingency**.
**Final answer:** The formula $$((p \to n2) \lor (p \to q))$$ is a **contingency**.
