Question

Indicate whether the argument is valid or invalid. For valid arguments, prove that the argument is valid using a truth table. For invalid arguments, give truth values for the variables showing that the argument is not valid.

**Logical Reasoning in Propositional Logic** Consider the following logical problem: 1. **p ↔ q** This represents a biconditional statement meaning "p if and only if q." 2. **p ∨ q** This is a disjunction meaning "p or q" (or both). 3. **∴ p** The symbol "∴" means "therefore." This is the conclusion, indicating that "p" is the result derived from the given statements. This problem illustrates logical reasoning, where the conclusion (p) is derived based on the provided premises (p ↔ q and p ∨ q).
