Hello, please answer the attached Discrete Math question completely and correctly. 

* If you follow all directions and answer the question correctly, I will give you a thumbs up. Thank you. 

**Instructions for Logical Proofs:** For each statement, identify the assumptions and the conclusions for proofs using contrapositive and contradiction methods. **Statement (b):** For all integers \( n \), if \( n^2 \) is odd, then \( n \) is also odd. **Tasks:** 1. **Prove using Contrapositive:** - **Assume:** \( n \) is even. - **Prove:** \( n^2 \) is even. 2. **Prove using Contradiction:** - **Assume:** \( n^2 \) is odd, and \( n \) is even. - **Reach a contradiction:** Analyze assumptions to show a logical inconsistency. **Note:** Please follow all directions and complete the exercises accurately. Thank you.
