Q4 The expression (-p^ g) → ¬r is equivalent to which of the following? Op^qvr OpvqVr Opv¬qV¬r Opn¬qV¬r Q5 We know that (q +r)^(-q+r) is equivalent to false because of which law? Biconditional law O Contradiction O Contrapositive law O Law of Excluded Middle

Which of the following statement needs to be corrected? A. The negation connective can only take one argument. B. Conjunction has higher precedence than disjunction. C. (PVQ) = (P) ^ (-Q) D. P⇒ Q and P^ Q are equivalent.

The table below shows the values of predicates Q, R, and S for every possible input. The domain for the input to each function is {1, 2, 3, 4). Ex: Q(3) is false because the entry in row 3, column Q is F. QRS 1F TF 2 FTF 3 FF F 4 TFF Determine the truth value of each expression. (1) ExVy(R(x)^((x + y) → ¬R(y))) Pick (2) ExVy(Q(x) ^ ((x + y) → ¬Q (y))) Pick (3) ExVy(-S(x) ^ ((x y) → S(y))) Pick
