Chapter 3: Problem 43

Use a truth table to determine whether each statement is a tautology, a self- contradiction, or neither. \(\sim(p \wedge q) \leftrightarrow(\sim p \wedge \sim q)\)

Short Answer

Expert verified
The given statement, \(\sim(p \wedge q) \leftrightarrow(\sim p \wedge \sim q)\), is neither a tautology nor a contradiction; it depends on the truth values of p and q to determine if the whole statement is true or false.

Step by step solution

01

Create a truth table

Our first step is to create a truth table that has all possible combinations of truth values for the variables p and q. This means our table will have four rows, with p and q being true or false in each combination.
02

Calculate the sub-expressions

Next, you need to calculate the truth values for the sub-expressions, \(p \wedge q\) and \(\sim p \wedge \sim q\), based on the truth values of p and q. And then, evaluate the negations of the resulting expressions.
03

Evaluate the final expression

Finally, you need to evaluate the truth of the entire statement, \(\sim(p \wedge q) \leftrightarrow(\sim p \wedge \sim q)\), for each row in the table, by determining whether the left part of the bicoditional is the same as the right part.
04

Interpret the table

The final step is to analyze the results. If the statement is true in all possible interpretation (all rows in the truth table), the statement is a tautology. If it is false in every interpretation, it's a self-contradiction. If it is sometimes true and sometimes false, then it is neither.
