1. Find the truth values of the following if the variables P, Q and R are all true:
(a) -P-Q
(b) -(PQ)
(c) (PAQ)^(-R)
(d) ~[~(~P)]
(e) (P=~Q) v-R (1) -P÷-Q
2. Draw a truth tables for the following:
(a) -(Pv-Q)
(b)~(PA-Q)
(c) ~[(PAQ) AR]
(d) Q-(Pv-Q)
(e) (PQ) (Q= P)
(f) [(PQ) ^~P)] = ~Q
(g) (PQ) (P⇒R)
(h) [PV (QA-P)] (PvQ)?
