Convert the following theorem to logical and prove by truth table:

. . . $\displaystyle (A \cap B)' \:=\:A' \cup B' $

. . $\displaystyle \begin{array}{c|c||cccccccc}

p & q & \sim & (p & \wedge & q) & \leftrightarrow & \sim p & \vee & \sim q \\ \hline

T & T & F & T & T & T & {\color{blue}T} & F & F & F \\

T & F & T & T & F & F & {\color{blue}T} & F & T & T \\

F & T & T & F & F & T & {\color{blue}T} & T & T & F \\

F & F & T & F & F & F & {\color{blue}T} & T & T & T \\ \hline
