Ris symmetric, but not reflexive and not transitive. O b. Ris not reflexive, not symmetric, and not transitive. Oc Ris reflexive, symmetric, and transitive. O d. Ris symmetric and transitive, but not reflexive. What is the truth value of (Pv-P)AQ? A. True B. False C. Unknown Select one: a. Unknown O b. False . True Is the following statement a tautology, contingent or contradiction? ((P^~Q) = R) = (P = (Q v R)) Select one: O a. a contingent Ob. a tautology O c. a contradiction What is simplest form of the logical expression -(-(PVQA-Q)? A. -(PvQ) B. PvQ C. PA-Q D. -(-PVQ) E. None of the above Select one: O a. D O b. B O c. E O d. A O e. C Which of the following rules is used in the following proof/conclusion: If Caz is unsure of an address then Caz will phone. (given).
