& \text { which were on time } & \text { which were late } \
\hline \text { Podunk Airlines } & 33 & 6 \
\text { Upstate Airlines } & 43 & 5
\end{array}$

The probability of selecting a flight that arrived on time is the number of flights that arrived on time divided by the total number of flights. From the table, we see that 33 + 43 = 76 flights arrived on time out of a total of 87 flights. Therefore, the probability of selecting a flight that arrived on time is 76/87.
