We have said what it means for a formula F to be: (1) a tautology, (2) contradictory. That F is a tautology and that G is contradictory represent two extreme poles of the spectrum of truth values for formulas in sentential logic. Most formulas involving sentences in English are neither tautologies nor contradictory. So, call a formula F satisfiable or contingent if its truth function has value 1 under at least one truth value assignment to its component simple sentences. It follows that a formula F is unsatisfiable if its truth function has value 0 under every truth value assignment to its component simple sentences. Your task is to use truth tables to determine whether the following formulas are: tautologies, contradictory (unsatisfiable) or contingent (satisfiable). (f) (¬¬p → p) (g) (p ∧ ¬p) (h) (p → (q → p)) (i) ((p ∧ q) ∧ (¬p ∨ ¬q)) (j) ((p ∨ q) → (¬p ∧ ¬q))
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.
Construct an argument which a. Satisfies the validity condition; b. Does not satisfy the validity condition c. Satisfies the validity condition but not the truth condition; d. Satisfies both the validity and the truth conditions. This is all about Valid Arguments and Fallacies (General Mathematics)
(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
Two compound statements are not logically equivalent if [Choose the most appropriate answer] Both the statements are tautology. O Both the statements ate contradiction. O Both the statements have at least one the corresponding truth values are different.. O Both the statements have same corresponding truth values.
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.
