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

If a flight is selected at random, find the probability that the flight will arrive on time.
A) $\frac { 11 } { 76 }$
B) $\frac { 76 } { 87 }$
C) $\frac { 43 } { 87 }$
D) None of the above is correct.

To find the probability that a flight will arrive on time, add the number of flights that arrived on time for both airlines (33 + 43 = 76) and divide by the total number of flights (33 + 6 + 43 + 5 = 87). This gives $\frac{76}{87}$.
