Question

What will be the input of $A$ and $B$ for Boolean expression

• A. $0,0$
• B. $0,1$
• C. $1,0$
• D. $1,1$

Answer 1

The correct option is A $0,0$

$\left(\overline{A+B}\right)\left(\overline{A.B}\right)=1$

Answer can be formed by trial and error.

$\left(A\right)(0,0)\Rightarrow A=0,B=0\left(\overline{0+0}\right)\left(\overline{0.0}\right)=\left(\overline{0}\right)\left(\overline{0}\right)=1.1=1$
