Find the indicated probability. Express your answer as a simplified fraction unless otherwise noted.
-The following table contains data from a study of two airlines which fly to Small Town, USA. $$\begin{array} { l | c c }
& { \text { Number of flights Number of flights } } \
& \text { which were on time } & \text { which were late } \
\hline \text { Podunk Airlines } & 33 & 6 \
\text { Upstate Airlines } & 43 & 5
\end{array}$$ If one of the 87 flights is randomly selected, find the probability that the flight selected is an Upstate Airlines flight given that it was late.
A) $\frac { 5 } { 87 }$
B) $\frac { 5 } { 11 }$
C) $\frac { 5 } { 48 }$
D) None of the above is correct.

The probability that the flight selected is an Upstate Airlines flight given that it was late is:P(Upstate Airlines | late) = P(Upstate Airlines and late) / P(late)= (5 / 87) / (11 / 87)= 5 / 11
