What is logically equivalent to P and Q?
A compound proposition that is always True is called a tautology. Two propositions p and q are logically equivalent if their truth tables are the same. Namely, p and q are logically equivalent if p ↔ q is a tautology. If p and q are logically equivalent, we write p ≡ q.
What are some true or false questions?
True or false questions are queries that display a statement before asking whether that statement is correct or incorrect.
