A) \[X=0,\,Y=1\]
B) \[X=1,\,Y=1\]
C) \[X=1,\,Y=0\]
D) \[X=0,\,Y=0\]
Correct Answer: C
Solution :
The truth table can be written as\[X\] | \[Y\] | \[\bar{X}\] | \[\bar{Y}\] | \[P=\bar{X}+Y\] | \[Q=\overline{X.Y}\] | \[R=\overline{P+Q}\] |
0 | 1 | 1 | 0 | 1 | 1 | 0 |
1 | 1 | 0 | 0 | 1 | 1 | 0 |
1 | 0 | 0 | 1 | 0 | 0 | 1 |
0 | 0 | 1 | 1 | 1 | 1 | 0 |
