Cite two arguments you’ve heard of lately. Prove the argument if it’s logically correct by:1. Translating to symbolic logic.2. Determining the rules of inference followed (if there’s any).a. If the argument is logically incorrect, state the error made, or the changes that needs to bedone.
Use truth tables to verify the following logical equivalences. Include a few words of explanation with your answers. (a) p- q = mp V a P9 ~p ~p V q F F F FTT OF F FF F The truth table shows that p - q and p V q always do not always have the same truth values. Therefore they are are not logically equivalent.
4. Construct a truth table for each statement: a. If you do not study or do not go to sleep by 12 pm., then you will not get an A (g → ~p) A r b.
• Convert the following statements to symbols. Use a truth table to show that the statement is a tautology. 1. Either it will rain tomorrow or it will not rain tomorrow. Let: p: Let : p: Symbols: Construct a truth table. P
In propositional logic, a contradiction is a compound proposition that is always false, no matter what the truth values of the propositional variables that occur in it are. Show by means of a truth table that p ∧ ￢ (q ∨ p) is a contradiction.
For the following logical statement draw the truth table, write down the canonical disjunc tive and conjunctive forms and the logical circuit for this statement.
Help please
Using Truth Tables, show that the following premises leads to tautology: (A ∧ ¬C) ∨ ((B ∨ C) ∨ ¬(C ∨ A))
Find the truth table of the following logical expression: (¬pV¬q) → (p→¬q) · (Note: Type T for true or F for false) pa(pv¬q) → (p→¬q) TT TF FF
4. Write each statement in symbolic form, and use truth tables to determine if they are logically equivalent: (define any variables you use) A: If you study hard and do all homework, then you will pass the class. B: If you study hard and did not pass the class, then you did not do all your homework.

Check all the statements that are true: A. It is possible to define disjunction using only negations and conjunction. B. Domain-restricted universal quantification is logically equivalent to the unrestricted universal quantification of a conditional. C. (p → a) v (p → →q) is a tautology. D. The negation of a conjunction is the disjunction of the negations. E. Inverse and converse are logically equivalent. F. A conditional is false when both premise and conclusion are false. G. The contrapositive is the inverse of the converse. H. A predicate is a proposition-valued function. I. Domain-restricted existential quantification is logically equivalent to the unrestricted existential quantification of a conditional. J. (pq) ^ (pq) is a contradiction.
