Smart answer::
Output of and gate is high when all the inputs of the and gate is high.
Output of and gate is high when all the inputs of the and gate is high.

In AND gate Y=A*B.
When A=HIGH & B=HIGH then the output Y=HIGH.
When A=HIGH & B=HIGH then the output Y=HIGH.

Only if all the inputs are high then only the and gate output is high.

AND Gate is enable only when their all inputs are high.

For the output of and gate to be high we need all 1 because by the combination of any 0 in case of and we get a 0 that is low output.

simple logic for xor ...
suppose A xor B = AB'+BA'
That is if both A and B Value is same then result is same
suppose A xor B = AB'+BA'
That is if both A and B Value is same then result is same

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.

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.

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