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

Weegy: True

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. [http://en.wikipedia.org/wiki/Proposition?] 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: The sentence "P ? Q" is best read as (Points : 1) If P then Q If Q then P P or Q P if and only if Q

User: A conditional sentence with a false antecedent is always (Points : 1) true. false. Cannot be determined. not a sentence

Weegy: Cannot be determined.

User: A conditional sentence with a false antecedent is always (Points : 1) true. false. Cannot be determined. not a sentence

Weegy: Cannot be determined.

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. [ http://answers.yahoo.com/question/index?qid=20110617184035AAQyL7t ]

Weegy: Cannot be determined.

User: Truth tables can be used to examine (Points : 1) inductive arguments. deductive arguments. abductive arguments. All of the above

Weegy: deductive arguments.

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

Weegy: True

User: The truth table for a valid deductive argument will show (Points : 1) wherever the premises are true, the conclusion is true. that the premises are false. that some premises are true, some premises false. wherever the premises are true, the conclusion is false.

Weegy: (D)premises are true and conclusion is true
