Question

Find the truth value:
If $3\times 6=20$, then $2+7=9$.

• A. T
• B. F
• C. T or F
• D. T and F

Answer 1

The correct option is A T

Let $p:3\times 6=20$
$q:2+7=9$
"If $p$ then $q$" can be written as $p\Rightarrow q$

$p$	$q$	$p\Rightarrow q$
T	T	T
T	F	F
F	T	T
F	F	T

$\because p$ is false and $q$ is true; truth value of "If $p$ then $q$" is T.
