If the truth value of the compound statement [(p q) (q r) r] (p q) is false, then the truth values of the statement patterns (p q) (q r) and (p r) (q p) are, respectively ...

Options

  1. A(T, T)
  2. B(T, F)
  3. C(F, T)
  4. D(F, F)

Correct answer

B. (T, F)

Step-by-step solution

The given compound statement is [(p q) (q r) r] (p q) . An implication X Y is false if and only if X is true and Y is false. Thus, (p q) (q r) r is true and p q is false. For the conjunction (p q) (q r) r to be true, each of its components must be true: r is true r = F q r is true q F is true q = F p q is true p F is true p = F Checking the second part with these values: p q = F T = F , which satisfies the condition that Y is false. So, the truth values are p = F , q = F , r = F . Now, evaluating the first statemen
