Draw a three$-$variable truth table for the Boolean expression $A*B+A*BA*B+A\frac{*}{b}ar(B)*C=Y*C=Y.$

Write the keyboard version of the Boolean expression $A\frac{*}{b}ar(B)\frac{+}{b}ar(A)*B\frac{*}{b}ar(C)=Y.$

Write the keyboard version of the Boolean expression

$\frac{?}{\text{b}\text{a}\text{r}}(A*B+A*(\frac{?}{\text{b}\text{a}\text{r}}(B))*(\frac{?}{\text{b}\text{a}\text{r}}(C)))=Y.$
