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.
