Mathematics Question on mathematical reasoning

If the truth value of the statement P(pr)P \to ( \sim p \vee r) is false(F), then the truth values of the statements p,q,rp, q, r are respectively :

A

F, T, T

B

T, F, F

C

T, T, F

D

T, F, T

Answer

T, T, F

Explanation

Solution

P(qr)P \to (\sim q \vee r)
p(qr)\sim p \vee (\sim q \vee r)
pF qF rF}pT qT rF}\left.\begin{aligned} \sim p \to F \\\ \sim q \to F \\\ r \to F \end{aligned}\right\rbrace \Rightarrow \left.\begin{aligned} p \to T \\\ q \to T \\\ r \to F \end{aligned}\right\rbrace
