For 3-input AND Gate: The output Y = A * B * C
A B C Y
0 0 0 0
0 0 1 0
0 1 0 0
0 1 1 0
1 0 0 0
1 0 1 0
1 1 0 0
1 1 1 1 <== On this case only the output will be HIGH.
Therefore, the answer is 1 possibility.
A B C Y
0 0 0 0
0 0 1 0
0 1 0 0
0 1 1 0
1 0 0 0
1 0 1 0
1 1 0 0
1 1 1 1 <== On this case only the output will be HIGH.
Therefore, the answer is 1 possibility.
