Question

Identify the correct steps involved while proving (p v ¬q) (q v ¬) a (r v -p) is true when p, q, and r have the same truth value and it is
false otherwise. (Check all that apply.)
Check All That Apply
We should prove that (p v -q) ^ (q v ¬) ^ (r v¬p) is true if and only if p, q, and rhave the same truth value.
Suppose p, q, and rare all true. Then, (p v -q) ^ (q v ¬) ^ (r v ¬p) is true as each clause has an unnegated variable.
Suppose p, q, and rare all true. Then, (p v ¬9) ^ (q v ¬) ^ (r p) is false as each clause has an unnegated variable.
Suppose p, q, and rare all false. Again, (p v ¬q) ^ (q v ¬) ^ (r v ¬p) is true as each clause has a negated variable.
Now, suppose one of the variables p, q, or ris true and the other two are false. Then, the clause that contains the negation
of the true variable will be false.

Which of the following statement is false? A) An argument is a set of initial statements, called premises, followed by a conclusion. An argument is valid if and only if in every case where all the premises are true, the conclusion is true. Otherwise, the B argument is invalid. Given a truth table representing an argument, the rows where all the premises are true are called the critical rows. If you see an argument in the form of a rule of inference, you know it's invalid.
