Solution Steps

To complete the truth table, we need to evaluate the logical expressions for each combination of truth values for \( q \) and \( r \). The expression \( q \wedge r \) represents the logical AND operation between \( q \) and \( r \). The expression \( r \wedge (q \wedge r) \) is the logical AND operation between \( r \) and the result of \( q \wedge r \).

Step 1: Evaluate \( q \wedge r \)

For each combination of truth values for \( q \) and \( r \), evaluate the logical AND operation \( q \wedge r \):

  • When \( q = \text{True} \) and \( r = \text{True} \), \( q \wedge r = \text{True} \).
  • When \( q = \text{True} \) and \( r = \text{False} \), \( q \wedge r = \text{False} \).
  • When \( q = \text{False} \) and \( r = \text{True} \), \( q \wedge r = \text{False} \).
  • When \( q = \text{False} \) and \( r = \text{False} \), \( q \wedge r = \text{False} \).
Step 2: Evaluate \( r \wedge (q \wedge r) \)

Using the results from Step 1, evaluate the expression \( r \wedge (q \wedge r) \):

  • When \( q = \text{True} \) and \( r = \text{True} \), \( r \wedge (q \wedge r) = \text{True} \).
  • When \( q = \text{True} \) and \( r = \text{False} \), \( r \wedge (q \wedge r) = \text{False} \).
  • When \( q = \text{False} \) and \( r = \text{True} \), \( r \wedge (q \wedge r) = \text{False} \).
  • When \( q = \text{False} \) and \( r = \text{False} \), \( r \wedge (q \wedge r) = \text{False} \).

Final Answer

The completed truth table is:

\[ \begin{array}{|c|c|c|c|} \hline q & r & q \wedge r & r \wedge (q \wedge r) \\ \hline \text{True} & \text{True} & \text{True} & \text{True} \\ \hline \text{True} & \text{False} & \text{False} & \text{False} \\ \hline \text{False} & \text{True} & \text{False} & \text{False} \\ \hline \text{False} & \text{False} & \text{False} & \text{False} \\ \hline \end{array} \]

\(\boxed{\text{Truth table completed}}\)
