Use the truth table method to decide whether the following · forms are tautologies, contradictions, or contingencies. *a. p > (9= p) b. (o'q) · (~p"~9) *C. ~(p » (O' q) d. (p=~9) "(~p=~9) *e. ((p = q) · (q = p)) = (p'q) f. (p = q) = (p=~9) | *g. (p:/qY )) = ((p:g) v(p:)) h. ((pvn) = q) •~(~q~) *i. ((p'q) '~ 1) = (pv (p '~ )) j. ((pvq) • ~ 1) = (pv (q:~;)) *k. [p. (q'~)] = [((p.5) · (qv~ r)) °((p :~s) · (q"~)))
