Question
Please kindly answer both questions. If not do number 1
The image contains two logical propositions and questions regarding their validity and equivalence. 1. **Logical Equivalence**: - Problem: Show that the propositions \( p \) and \( p \lor (p \land q) \) are logically equivalent. - Explanation: This involves demonstrating that both propositions have the same truth values in all possible scenarios. This can be done by constructing a truth table or using logical identities. 2. **Argument Validity**: - Question: Is the following argument valid? - Premises: 1. \( p \rightarrow q \) 2. \( p \lor q \) - Conclusion: \( q \) - Explanation: To determine validity, analyze if the conclusion \( q \) logically follows from the premises. This often involves using rules of inference such as modus ponens, modus tollens, disjunctive syllogism, etc. No graphs or diagrams are present in the image.
