Question:
The negation of the boolean expression $\sim \mathrm{s} \vee(\sim \mathrm{r} \wedge \mathrm{s})$ is equivalent to:
Correct Option: , 2
Solution:
$\sim(\sim \mathrm{S} \vee(\sim \mathrm{r} \wedge \mathrm{S}))$
$\mathrm{s} \wedge(\mathrm{r} \vee \sim \mathrm{s})$
$(s \wedge r) \vee(s \wedge \sim s)$
$(s \wedge r) \vee(c)$
$(s \wedge r)$
