Math Problem Statement
If p is true and q is false, find the truth value of p ∨ ¬q.
Solution
The problem asks to find the truth value of the logical expression given that:
- is true,
- is false.
Let’s break down the expression:
-
Negation of (i.e., ): Since is false, (not ) is true.
-
Disjunction (OR) :
- The logical OR () is true if at least one of the operands is true.
- is true, and is also true.
- Since both and are true, the entire expression is true.
Final Answer: True

Tip: Always remember that in logical OR (), if either value is true, the whole expression evaluates to true.
