Math Problem Statement

Tentukan tabel nilai kebenaran dari (P ∧ Q) → (Q ∨ ¬R)

Solution

The question in the image asks for a truth table to determine the truth values of a logical expression. The formula in the image can be interpreted as:

Tentukan tabel nilai kebenaran dari:
(PQ)(Q¬R)(P \land Q) \rightarrow (Q \lor \neg R)

This logical expression involves three propositions: PP, QQ, and RR, and includes the following operations:

  1. \land: Logical AND
  2. \lor: Logical OR
  3. ¬\neg: Negation
  4. \rightarrow: Logical implication

Steps to Create the Truth Table:

  1. List all possible truth value combinations for PP, QQ, and RR.
  2. Compute PQP \land Q.
  3. Compute ¬R\neg R.
  4. Compute Q¬RQ \lor \neg R.
  5. Compute the final expression: (PQ)(Q¬R)(P \land Q) \rightarrow (Q \lor \neg R).

Let me construct the truth table for this expression. pandas as pd

Define all possible truth values for P, Q, and R

truth_values = [(P, Q, R) for P in [True, False] for Q in [True, False] for R in [True, False]]

Prepare the truth table

data = [] for P, Q, R in truth_values: P_and_Q = P and Q not_R = not R Q_or_not_R = Q or not_R final_result = not P_and_Q or Q_or_not_R # (P ∧ Q) → (Q ∨ ¬R) data.append([P, Q, R, P_and_Q, not_R, Q_or_not_R, final_result])

Create a DataFrame

columns = ["P", "Q", "R", "P ∧ Q", "¬R", "Q ∨ ¬R", "(P ∧ Q) → (Q ∨ ¬R)"] truth_table = pd.DataFrame(data, columns=columns)

import ace_tools as tools; tools.display_dataframe_to_user(name="Truth Table for Logical Expression", dataframe=truth_table)The truth table for the given logical expression has been created. Let me know if you have any questions or need further clarification!

Here are 5 related questions to expand on this topic:

  1. What are the key differences between logical conjunction (\land) and disjunction (\lor) in truth tables?
  2. How does the negation (¬\neg) operator affect the truth value of a proposition?
  3. Could you explain the behavior of logical implication (\rightarrow) in more detail?
  4. Can this logical expression be simplified using logical equivalences?
  5. How are truth tables used in computer science and digital circuit design?

Tip: Truth tables are a foundational tool for analyzing logical statements and are essential for understanding Boolean algebra and logic gates.
