Mathematical Logic And Boolean Algebra Question 54
Question: Let p and q be any two logical statements and $ r:p\to (\tilde{\ }p\vee q). $ If r has a truth value F, then the truth values of p and q are respectively:
Options:
A) F, F
B) T, T
C) T, F
D) F, T
Show Answer
Answer:
Correct Answer: C
Solution:
[c]  $ p\to (\tilde{\ }p\vee q) $  has truth value F. It means  $ p\to (\tilde{\ }p\vee q) $  is false. It means p is true and  $ \tilde{\ }p\vee q $  is false.
$ \Rightarrow p $  is true and both  $ \tilde{\ }p $  and q are false.
$ \Rightarrow p $  is true and q is false.
