A. The statement is not a tautology, since there is at least one combination of truth values for its components where the statement is false. B. The statement is a tautology, since it is true for all combinations of truth values of the components. C. The statement is not a tautology, since it is false for all combinations of truth values of the components. D. The statement is a tautology, since there is at least one combination of truth values for its components where the statement is true.
(a) Use a truth table to determine whether the following argument is valid. Be sure to indicate how you are reaching your conclusion. (Here t denotes a tautology) t → (~p V ~q) .. q → ~p (b) Use logical equivalences and standard forms to show that the following argument is valid. Fully justify each step of your claim. ~s → (r → ~p V ~q) .. S
Use the truth table test of validity to determine whether the following arguments are valid or invalid. To be invalid, the premises will be true, but the conclusion false. INSTRUCTIONS: 1. First, identify and define the type of Truth Functional Connective each symbol represents and type it in to the first table. 2. Then, create a Formal Method Test of validity table below each argument to determine whether the argument is valid or invalid. 3. Indicate whether the argument is valid or invalid. If the argument is invalid, highlight the area on the table that proves it. A row for each possible outcome [2"] → Use the pattern of half the rows to make half of the values in the column true → For the next column keep using the pattern of half Remember to Create: Type in the meaning of the symbol in the space provided.
