The output of AND gate is high and all the inputs are high or 1.

IF,
A=0,B=0,C=0 - 0
A=1,B=0,C=0 - 0
A=0,B=1, C=0 -0
A=1,B=1,C=0 - 0
A=1,B=0, C=1 -0
ONLY,
A=1,B=1,C=1 - 1(HIGH) BECAUSE A*B*C.
A=0,B=0,C=0 - 0
A=1,B=0,C=0 - 0
A=0,B=1, C=0 -0
A=1,B=1,C=0 - 0
A=1,B=0, C=1 -0
ONLY,
A=1,B=1,C=1 - 1(HIGH) BECAUSE A*B*C.

Output of an AND gate is high when all inputs are high a=1, b=1, c=1.

The Logic of and gate is when all the 3 inputs are high output is high when any one input is low output is low.

In AND gate any 2 IP are high op is high.

The AND Gate function is to multiply
exmaple
input output
0 0
1 1
exmaple
input output
0 0
1 1

A*B=1*1=1
C*A*B=1*1=1
C*A*B=1*1=1

If A=0 & B=0
then A*B=0*0=0 (since AND gate performs multiplication)
If A=1 & B=0
then also A*B=1*0=0.
If A=0 & B=1
then also A*B=0*1=0.
If A=1 & B=1
then only A*B=1*1=1.
then A*B=0*0=0 (since AND gate performs multiplication)
If A=1 & B=0
then also A*B=1*0=0.
If A=0 & B=1
then also A*B=0*1=0.
If A=1 & B=1
then only A*B=1*1=1.

Output of an AND gate is high when all inputs are high a=1, b=1, c=1.
Output of AND gate is = A*B*C = 1*1*1 = 1.
Output of AND gate is = A*B*C = 1*1*1 = 1.
