बूले के व्यंजक (Boolean expression) $p \vee(\sim p \wedge q )$ का निषेधन (Negation) निम्न में से किसके तुल्य है ?

A

$\sim p \vee \sim q$

B

$\sim p \vee q$

C

$\sim p \wedge \sim q$

D

$p \wedge \sim q$

(JEE MAIN-2020)

Solution

Negation of $\phi \vee(\sim p \wedge q )$

$p \vee(\sim p \wedge q )=( p \vee \sim p ) \wedge( p \vee q )$

$=(T) \wedge(p \vee q)$

$=(p \vee q)$

now negation of $( p \vee q )$ is

$\sim( p \vee q )=\sim p \wedge \sim q$
