The correct Answer is:
To determine which statement is equivalent to "p to q" (denoted as \( p \implies q \)), we will create a truth table and analyze the options. ### Step 1: Create the Truth Table for \( p \implies q \) 1. **Identify the possible values for \( p \) and \( q \)**: - Each statement can either be True (T) or False (F). - Since there are two statements, there are \( 2^2 = 4 \) combinations. 2. **List the combinations**: - \( p \) can be T or F. - \( q \) can also be T or F. - The combinations are: - \( p = T, q = T \) - \( p = T, q = F \) - \( p = F, q = T \) - \( p = F, q = F \) 3. **Determine the truth values for \( p \implies q \)**: - The implication \( p \implies q \) is only false when \( p \) is true and \( q \) is false. In all other cases, it is true. - The truth values for \( p \implies q \) are: - \( T \implies T \) = T - \( T \implies F \) = F - \( F \implies T \) = T - \( F \implies F \) = T 4. **Construct the truth table**: | \( p \) | \( q \) | \( p \implies q \) | |---------|---------|---------------------| | T | T | T | | T | F | F | | F | T | T | | F | F | T | ### Step 2: Analyze the Options Now we will analyze the options provided to find an equivalent statement to \( p \implies q \). 1. **Negation of \( q \)**: - Truth table for \( \neg q \): - \( q = T \) → \( \neg q = F \) - \( q = F \) → \( \neg q = T \) - This does not match \( p \implies q \). 2. **Negation of \( p \) or \( q \)**: - Truth table for \( \neg p \lor q \): - \( p = T, q = T \) → \( \neg p = F \), \( \neg p \lor q = T \) - \( p = T, q = F \) → \( \neg p = F \), \( \neg p \lor q = F \) - \( p = F, q = T \) → \( \neg p = T \), \( \neg p \lor q = T \) - \( p = F, q = F \) → \( \neg p = T \), \( \neg p \lor q = T \) - This does not match \( p \implies q \). 3. **Negation of \( p \) and \( q \)**: - Truth table for \( \neg p \land q \): - \( p = T, q = T \) → \( \neg p = F \), \( \neg p \land q = F \) - \( p = T, q = F \) → \( \neg p = F \), \( \neg p \land q = F \) - \( p = F, q = T \) → \( \neg p = T \), \( \neg p \land q = T \) - \( p = F, q = F \) → \( \neg p = T \), \( \neg p \land q = F \) - This does not match \( p \implies q \). 4. **Disjunction of \( \neg p \) and \( q \)**: - Truth table for \( \neg p \lor q \): - \( p = T, q = T \) → \( \neg p = F \), \( \neg p \lor q = T \) - \( p = T, q = F \) → \( \neg p = F \), \( \neg p \lor q = F \) - \( p = F, q = T \) → \( \neg p = T \), \( \neg p \lor q = T \) - \( p = F, q = F \) → \( \neg p = T \), \( \neg p \lor q = T \) - This matches \( p \implies q \). ### Conclusion The statement that is equivalent to \( p \implies q \) is \( \neg p \lor q \).

To determine which statement is equivalent to "p to q" (denoted as \( p \implies q \)), we will create a truth table and analyze the options. ### Step 1: Create the Truth Table for \( p \implies q \) 1. **Identify the possible values for \( p \) and \( q \)**: - Each statement can either be True (T) or False (F). - Since there are two statements, there are \( 2^2 = 4 \) combinations. ...
