Use the data in the table categorizing cholesterol levels by the ages of the individuals in a study. If one person from the study is chosen at random, find the probability of the given event.
-The person has elevated cholesterol. $$\begin{array} { | l | c | c | c | }
\hline & \begin{array} { c }
\text { Normal } \
\text { Cholesterol }
\end{array} & \begin{array} { c }
\text { Elevated } \
\text { Cholesterol }
\end{array} & \text { Total } \
\hline \begin{array} { l }
\text { 30 and } \
\text { under }
\end{array} & 11 & 5 & 16 \

\end{array}$$
A) $\frac { 113 } { 200 }$
B) $\frac { 87 } { 200 }$
C) $\frac { 87 } { 113 }$
D) $\frac { 26 } { 113 }$
