![Using truth tables, or in any other way, prove that each of the following
compound propositions is not a tautology.
These implications are common logical fallacies (errors in reasoning)
since the conclusion does not follow logically from the set of hypotheses.
a. [(P⇒ Q) ^ Q] ⇒ P.
b. [(PQ) ^ (~ P)] ⇒ (~ Q).
For each one of the logical fallacies in part (iii) of this question give an
example of a "real life" situation where such an error can occur.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fce8827c4-1422-4db4-bd87-5e9d779d6c3b%2Fe3e184b7-c459-4822-adc9-5e471cf14be8%2Fl2next_processed.png&w=3840&q=75)
