Everyone with good reading habit visits Book Exhibition and every book buyer has a good reading habit. Can we infer that all who visit Book Exhibition are book buyers?
Show Hint
In logic problems, implication works one way unless explicitly stated otherwise.
Concept:
Logical reasoning with conditional statements.
Explanation:
Given:
\begin{itemize}
\item Good readers $\rightarrow$ Visit exhibition
\item Book buyers $\rightarrow$ Good readers
\end{itemize}
So:
\[
Book\ buyers \rightarrow Good\ readers \rightarrow Visit\ exhibition
\]
But reverse is not true.
Some visitors may not be book buyers.
Hence, the conclusion is incorrect.
