Use the table to find the probability.
-The following table contains data from a study of two airlines which fly to Small Town, USA. $\begin{array}{l|cc}
& \begin{array}{r}
\text { Number of flights } \
\text { arrived on time }
\end{array} & \begin{array}{r}
\text { Number of flights } \
\text { arrived late }
\end{array} \
\hline \text { Podunk Airlines } & 33 & 6 \
\text { Upstate Airlines } & 43 & 5
\end{array}$

If a flight is selected at random, find the probability that the flight is on Upstate Airline given the flight is late.
A) $\frac { 5 } { 11 }$
B) $\frac { 5 } { 87 }$
C) $\frac { 5 } { 48 }$
D) None of the above is correct.
