The image features a truth table and a logic diagram. ### Truth Table Explanation The truth table on the left evaluates the logical expression \((p \lor q) \rightarrow \neg q\). It consists of the following columns: - **p**: Represents the truth value of proposition \(p\). - **q**: Represents the truth value of proposition \(q\). - **(p ∨ q)**: Logical OR operation between \(p\) and \(q\). - **(p ∨ q) → ¬q**: Logical implication from \((p \lor q)\) to \(\neg q\). The possible combinations of truth values for \(p\) and \(q\) are listed, with corresponding results for each expression. #### Rows: 1. **Row 1**: \(p = T\), \(q = T\) 2. **Row 2**: \(p = T\), \(q = F\) 3. **Row 3**: \(p = F\), \(q = T\) 4. **Row 4**: \(p = F\), \(q = F\) ### Logic Diagram Explanation The diagram on the right provides logic symbols for constructing the expression: - **\(\sim\)**: Represents NOT. - **□ → □**: Represents an implication. - **□ ∨ □**: Represents OR. These symbols can be used to construct or visualize logical expressions similar to the one presented in the truth table. The buttons (\(\times\), reset, and help) are likely used for clearing, resetting, or obtaining assistance with the tool.
