Math Problem Statement

p V (q ^r) in a truth table

p is false q is true r is false

Solution

Let's break down the logical expression p(qr)p \vee (q \land r) and evaluate it step by step, given that:

  • p=falsep = \text{false}
  • q=trueq = \text{true}
  • r=falser = \text{false}

We need to calculate the expression using the following logical operators:

  • \vee: OR
  • \land: AND

Step-by-step evaluation:

  1. Evaluate qrq \land r: qr=truefalse=falseq \land r = \text{true} \land \text{false} = \text{false} (AND requires both operands to be true, so the result is false.)

  2. Evaluate p(qr)p \vee (q \land r): pfalse=falsefalse=falsep \vee \text{false} = \text{false} \vee \text{false} = \text{false} (OR requires at least one operand to be true, but both are false, so the result is false.)

Thus, the final result of p(qr)p \vee (q \land r) is false.

  2. How does the truth table for qrq \land r look?
  3. Can you explain the difference between \vee (OR) and \land (AND)?
  4. What if rr were true instead of false—how would that affect the result?
  5. How does this type of logical expression apply to real-world situations, such as decision-making?

Tip: When working with logical operators, remember that AND requires both operands to be true, while OR only requires one.
