Are the following statement forms logically equivalent: p ? q ? p and p ? (? p ? q)? Include a truth table and a few words explaining how the truth table supports your answer.
What will be an ideal response?
The statement forms are not logically equivalent.
Truth table:
Explanation: The truth table shows that p ? q ? p and p ? (? p ? q) have different truth values in
rows 3 and 4, i.e, when p is false. Therefore p ? q ? p and p ? (? p ? q) are not logically equivalent.
