Pick an option to check your answer.
Answer & Solution
Correct Answer
(D)
\(A\) \(B\) \(Y\) \(0\) \(0\) \(1\) \(0\) \(1\) \(0\) \(1\) \(0\) \(0\) \(1\) \(1\) \(1\)
Step-by-step Solution
Detailed explanation
\(y=\overline{(A+\overline{A+B})+(\overline{B+\overline{A+B})}}\)

\(y=(A+\overline{A+B}) \cdot(B+\overline{A+B})\)
| \(A\) | \(B\) | \(Y\) |
| \(0\) | \(0\) | \(1\) |
| \(0\) | \(1\) | \(0\) |
| \(1\) | \(0\) | \(0\) |
| \(1\) | \(1\) | \(1\) |
