Question and answer
If P is false, and Q is false, the truth-value of "P ?Q" is false. true. Cannot be determined. All of the above.
For clarification, the following paragraph is taken from Wikipedia. Biconditional joins two simpler propositions, and we write "above example (sic)", which is read "P if and only if Q". [ It expresses that P and Q have the same truth-value, thus P if and only if Q is true in cases 1 and 4, and false otherwise. 1. P is true and Q is true 2. P is true and Q is false 3. P is false and Q is
true 4. P is false and Q is false Here is my answer... Therefore, if P is false and Q is false, the truth-value of P iff (if and only if) Q is true. "True". ]
