Math Problem Statement
Evaluate the truth value of the following logical expression: (p∨q)⇒¬p
Question 6Select one:
False
None of the above
All of the above
True
Solution
To evaluate the truth value of , let's analyze it using truth values of and .
Step-by-Step Solution
-
Expression Analysis:
- represents the logical "or" of and , which is true if at least one of or is true.
- represents the negation of , which is true when is false.
-
Implication Analysis:
- The implication will be true unless is true and is false.
- The implication is only false when the antecedent is true and the consequent is false.
-
Truth Table:
Let's construct a truth table to evaluate the expression for all possible values of and .
T | T | T | F | F |
T | F | T | F | F |
F | T | T | T | T |
F | F | F | T | T |
- Result:
- The expression is false when is true (whether is true or false).
- Therefore, the truth value of the expression is False.
Answer
The correct answer is:
- False

- Evaluate using a truth table.
- Determine the truth value of .
- For which values of and is true?
- Explain how the truth table changes when using an exclusive OR instead of inclusive OR.
Tip: For any implication , remember that it’s false only when is true, and is false.
