Math Problem Statement

Suppose that statement p is false and statement q is true. Evaluate the truth value of: (p → q) ⊕ (q → p)

Solution

The problem asks to evaluate the truth value of the logical expression:

(pq)(qp)(p \rightarrow q) \oplus (q \rightarrow p)

Given that:

  • pp is false,
  • qq is true.

We need to break down each part of the expression:

  1. Implication pqp \rightarrow q:

    • The implication pqp \rightarrow q is true when pp is false, regardless of qq's truth value. Since pp is false and qq is true, pqp \rightarrow q is true.
  2. Implication qpq \rightarrow p:

    • The implication qpq \rightarrow p is false when qq is true and pp is false. Since qq is true and pp is false, qpq \rightarrow p is false.
  3. Exclusive OR (XOR, \oplus):

    • The XOR operation is true if one of the operands is true and the other is false. Since pqp \rightarrow q is true and qpq \rightarrow p is false, the XOR evaluates to true.

Thus, the truth value of the expression is true.

Let me know if you'd like further clarification or details! Here are five related questions to explore:

  1. What are the truth tables for the logical operations \rightarrow and \oplus?
  2. How does the truth value of pqp \rightarrow q change if both pp and qq are true?
  3. What happens if both pp and qq are false in the expression (pq)(qp)(p \rightarrow q) \oplus (q \rightarrow p)?
  4. Can you give another example where XOR between two implications results in false?
  5. What is the difference between the logical operations AND, OR, and XOR?

Tip: In logic, implications (\rightarrow) are always true when the premise is false, no matter the conclusion.
