9. True or False: “There is no way to assign truth values to the atomic components of an equivalent pair of formulas such that one turns out true and the other turns out false’?

Why the reversed logic? Why can't it be answered with C(10, 4) = 210?

For the second picture I only need numbers #11 and #13 to be done For each proof, you must include (i.e., write) the premises in that proof. I do not want to see any proofs without premises. Do not use any transformation rules (e.g. contraposition) in your proof other than DN. Only use the eight inference rules. YOU CANNOT USE CONDITIONAL PROOF (CP), INDIRECT PROOF (IP), OR ASSUMED PREMISES (AP).
