[8] Use truth tables to establish whether the following statement form is a tautology, a contradiction, or neither: ((~p ^ q) ^ (q ^ r)) ^ ~q.

Q: Use truth tables to determine if (p O q) V (q → r) and (p ^ q ^ F) are equivalent.

A: Let us consider two proposition P and Q then  the truth table of following is given as P Q P⊕Q…

Q: Fill in the blank to show how to negate each of the following statements. ~(~A) = ~(A → B) =

A:

Q: Show, using truth tables, that (a) ¬(p V q) A r = -p^ (¬q ^ r), (b) -4 v (q V p) is a tautology.

A: (a) To show ¬p∨q∧r≡¬p∧¬q∧r using Truth tables. (b) To show ¬q∨q∨p is a tautology using Truth tables.
