What is the purpose of a truth table?
A truth table shows how the truth or falsity of a compound statement depends on the truth or falsity of the simple statements from which it's constructed.
What are the five logical connectives?
The five logical connectives are negation (¬), union (∧), disjunction (∨), implication (→), and biconditional (↔).
What is the truth table for the implication connective?
P Q P → Q 1 1 1 1 0 0 0 1
What is the truth table for the negation connective?
P ¬P 1 0 0 1
Which connective is represented by the symbol '∧' in the truth table?
Union
What is the truth table for the biconditional connective?
P Q P ↔ Q 1 1 1 1 0 0 0 1
What is the truth value of 'P ∧ Q' when P is true and Q is false?
Cannot be determined
Which connective is represented by the symbol '∨' in the truth table?
Disjunction
What is the truth value of 'P ∨ Q' when P is false and Q is false?
False

Study Notes
Purpose of a Truth Table
- A truth table is used to calculate the validity of logical arguments and to test the consistency of a set of statements.
Logical Connectives
- There are five basic logical connectives: implication (→), negation (¬), conjunction (∧), disjunction (∨), and biconditional ().
Implication Connective
- The implication connective is represented by the symbol '→' in a truth table.
- The truth table for the implication connective shows that if P is true and Q is false, then P → Q is false.
Negation Connective
- The negation connective is represented by the symbol '¬' in a truth table.
- The truth table for the negation connective shows that ¬P is true when P is false, and ¬P is false when P is true.
Conjunction Connective
- The conjunction connective is represented by the symbol '∧' in a truth table.
- The truth table for the conjunction connective shows that P ∧ Q is true when both P and Q are true, and false otherwise.
- The truth value of 'P ∧ Q' is false when P is true and Q is false.
Disjunction Connective
- The disjunction connective is represented by the symbol '∨' in a truth table.
- The truth table for the disjunction connective shows that P ∨ Q is false when both P and Q are false, and true otherwise.
- The truth value of 'P ∨ Q' is false when P is false and Q is false.
Biconditional Connective
- The biconditional connective is represented by the symbol '' in a truth table.
- The truth table for the biconditional connective shows that P Q is true when P and Q have the same truth value, and false otherwise.
Test your knowledge of truth tables for logical connectives with this quiz! Learn about the five main logical connectives, including negation, union, disjunction, implication, and biconditional. Practice constructing truth tables using binary logic and understand how the truth or falsity of compound statements is determined.
