User: What is the truth value of the sentence "P & ~ P"? (Points : 1) True False Cannot be determined Not a sentence

Weegy: True
audrey17|Points 954|

User: If P is false, and Q is false, the truth-value of "P ?Q" is (Points : 1) false. true. Cannot be determined. All of the above.

Weegy: 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". ]

User: . In the conditional "P ? Q," "Q is a (Points : 1) sufficient condition for Q. sufficient condition for P. necessary condition for P. necessary condition for Q.

Weegy: Max's explanation of "sufficiency" is very good. P doesn't have to be true for Q to be true, therefore it's not necessary. The truth table for a logical implication is: P|Q|P->Q ________ 1|1|1 1|0|0 0|1|1 0|0|1 P -> Q is true when P is false. [ ]
