Understand the Problem

The question is asking to determine the truth value of the logical statement (p ∨ q) → q, given specific truth values for p and q. This involves understanding and applying logical operations.

Answer

False
Answer for screen readers

The truth value of the statement ( (p \lor q) \rightarrow q ) is ( \text{False} ).

Steps to Solve

  1. Identify the given truth values We are given that ( p ) is true and ( q ) is false:
  • ( p = \text{True} )
  • ( q = \text{False} )
  1. Evaluate ( p \lor q ) The logical disjunction (OR) is true if at least one of the operands is true. $$ p \lor q = \text{True} \lor \text{False} = \text{True} $$

  2. Evaluate ( (p \lor q) \rightarrow q ) Now we evaluate the implication (→). An implication is false only if the first operand is true and the second operand is false: $$ (p \lor q) \rightarrow q = \text{True} \rightarrow \text{False} $$

  3. Determine the truth value of the implication Since the first part is true and the second part is false, the implication evaluates to false: $$ \text{True} \rightarrow \text{False} = \text{False} $$

The truth value of the statement ( (p \lor q) \rightarrow q ) is ( \text{False} ).

More Information

The logical implication states that if ( p \lor q ) is true, then ( q ) must also be true. Here, ( p \lor q ) is true, but ( q ) is false, making the whole statement false. This is a fundamental concept in propositional logic.

Tips

  • One common mistake is to misinterpret the truth value of implications. Remember that an implication is false only when the first part is true and the second is false.
