To determine

To calculate:The required values and complete the table using the information: $n\left(A\right)=50$, $n\left(B\right)=45$, $n\left(A\cup B\right)=80$, and $n\left(U\right)=100$.

$\begin{array}{rrrr}\hfill & \hfill A& \hfill A^{\prime }& \hfill \text{Totals}\\ \hfill B& \hfill & \hfill & \hfill \\ \hfill B^{\prime }& \hfill & \hfill & \hfill \\ \hfill \text{Totals}& \hfill & \hfill & \hfill \end{array}$
