Laws and Theorems of Boolean Algebra

The boolean expression $\overline{\mathit{A}\mathit{B}\mathit{C}}$ can be simplified as-

If $A=1\text{,} B=0\text{,}$ then in terms of Boolean algebra $AB+\overline{A}·A$ equals
 

According to the laws of Boolean algebra, the expression $(A+AB)$  is equal to

In the Boolean algebra $Y=A·B$  indicates that -

If $A=B=1$ then in terms of Boolean algebra $A+\overline{B}$  equals

In boolean algebra $Y=A+B$ implies that
