If p q is false and q r is false, then the truth value of (p, q, r) is...
Options
- A(T, F, T)
- B(F, T, F)
- C(F, F, T)
- D(F, T, T)
Correct answer
C. (F, F, T)
Step-by-step solution
The implication p q is given as false. An implication A B is false if and only if A is true and B is false. Therefore, p is true and q is false. Since p is true, p must be false ( F ). Thus, p = F and q = F . The biconditional q r is given as false. A biconditional A B is false if and only if A and B have opposite truth values. Since q is false, r must be true ( T ). The truth values of (p, q, r) are (F, F, T) . Answer: (F, F, T)
