Question

Just started learning this topic, but still confuses me a bit. Please help figure out the answer to this two problems.

Select the following statements that are true. pp is a contradiction. p^q^p is a contingency. (p^p) →q is a tautology. pq is the contrapositive of p→→→q Op →→q is the inverse of p→ q Match each of the following compound propositions with the logically equivalent one. > V (p→q) P→q (pV¬q) (p^(-(p^q))) ¬p ^ (p V q) 1. p/q 2. p V q 3. pV -q 4. p^ q
