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 will arrive on time given that they fly with Upstate airlines.
A) $\frac { 11 } { 76 }$
B) $\frac { 43 } { 48 }$
C) $\frac { 43 } { 87 }$
D) None of the above is correct.

Quizplus · Accepted Answer

The probability that a flight will arrive on time given that it is with Upstate Airlines is calculated by dividing the number of Upstate Airlines flights that arrived on time (43) by the total number of Upstate Airlines flights (43 arrived on time + 5 arrived late = 48). Therefore, the probability is $\frac{43}{48}$.
