Math Problem Statement

Select the truth table for the following expression: (p ⇒ q) ∨ r

Solution

The expression in the image is: (pq)r(p \Rightarrow q) \lor r.

Let's break this down to construct the truth table:

  1. pqp \Rightarrow q is a conditional statement that is false only when pp is true and qq is false, and true otherwise.
  2. \lor represents the logical "or" operator, which is true if at least one of the operands is true.

We need to evaluate (pq)r(p \Rightarrow q) \lor r for all possible combinations of truth values for pp, qq, and rr.

  • Column 4 shows the evaluation of pqp \Rightarrow q for each combination of pp and qq.
  • Column 5 shows the evaluation of (pq)r(p \Rightarrow q) \lor r, which takes the result of pqp \Rightarrow q and combines it with rr using logical "or."

Related Questions:

  1. How do you determine the truth value of a conditional statement like pqp \Rightarrow q?
  2. What are the truth tables for other logical operations, such as "and" (\land) or "not" (¬\neg)?
  3. How would the truth table change if the expression used \land instead of \lor?
  4. Can you explain the logical equivalence between ¬pq\neg p \lor q and pqp \Rightarrow q?
  5. How do logical operations apply in circuit design or programming conditions?

Tip:

In truth tables, conditional statements (pqp \Rightarrow q) are true whenever pp is false or when qq is true.
