$**$ Determine the truth values of the following symbolized statements. Let A$,$ B$,$ and C be true,

and X$,$ Y$,$ and Z be false. Please, show the process of calculation by using the letter $$T$$ for

$$true$,$ and $$F$$ for $$false$$ under each letter and operator. Please, underline your answer $($truth

value under the main operator$)$ and also make it into Bold font. $($# $2630,0\mathrm{.}3$ point for each

only when the whole process of truth value calculation is correctly demonstrated to support the

answer.$)$
