Introduction

Truth tables are a fundamental tool in logic and mathematics, used to evaluate the truth values of compound statements. In this article, we will focus on constructing a truth table for the given compound statement: $p \wedge \sim q$ . We will break down the process into manageable steps and provide a detailed explanation of each step.

Understanding the Compound Statement

The compound statement $p \wedge \sim q$ is a conjunction of two statements: $p$ and $\sim q$ . The symbol $\wedge$ represents the conjunction operator, which means "and". The symbol $\sim$ represents the negation operator, which means "not".

Breaking Down the Compound Statement

To construct the truth table, we need to break down the compound statement into its individual components. In this case, we have two components: $p$ and $\sim q$ .

$p$ is a simple statement that can be either true (T) or false (F).
$\sim q$ is a negated statement, which means it is the opposite of $q$ . If $q$ is true, then $\sim q$ is false, and if $q$ is false, then $\sim q$ is true.

Constructing the Truth Table

A truth table is a table that lists all possible combinations of truth values for the individual components of a compound statement. In this case, we have two components: $p$ and $q$ . We will list all possible combinations of truth values for $p$ and $q$ , and then evaluate the truth value of the compound statement $p \wedge \sim q$ for each combination.

Step 1: List All Possible Combinations of Truth Values

We will list all possible combinations of truth values for $p$ and $q$ in the following table:

$p$	$q$
T	T
T	F
F	T
F	F

Step 2: Evaluate the Truth Value of $\sim q$

We will evaluate the truth value of $\sim q$ for each combination of truth values for $p$ and $q$ .

$p$	$q$	$\sim q$
T	T	F
T	F	T
F	T	F
F	F	T

Step 3: Evaluate the Truth Value of $p \wedge \sim q$

We will evaluate the truth value of $p \wedge \sim q$ for each combination of truth values for $p$ and $\sim q$ .

$p$	$q$	$\sim q$	$p \wedge \sim q$
T	T	F	F
T	F	T	T
F	T	F	F
F	F	T	F

Conclusion

In this article, we constructed a truth table for the given compound statement: $p \wedge \sim q$ . We broke down the compound statement into its individual components, listed all possible combinations of truth values for the components, evaluated the truth value of each component, and finally evaluated the truth value of the compound statement. The resulting truth table shows that the compound statement $p \wedge \sim q$ is true only when $p$ is true and $q$ is false.

Discussion

Truth tables are a powerful tool in logic and mathematics, used to evaluate the truth values of compound statements. By constructing a truth table, we can determine the truth value of a compound statement for all possible combinations of truth values of its individual components. This can be useful in a variety of applications, such as:

Logic and mathematics: Truth tables are used to evaluate the truth values of compound statements in logic and mathematics.
Computer science: Truth tables are used to evaluate the truth values of logical expressions in computer science.
Decision-making: Truth tables can be used to evaluate the truth values of statements in decision-making scenarios.
