Question $47$

$1$ pts

Recall our model of Queueing Theory$/$Waiting Line Analysis from class.

Students must have their schedule approved by an academic advisor. It takes the advisor an average of $5$ minutes to approve a schedule. Students arrive at the advisor's office at a rate of $4$ per hour.

What is the probability that just one student will arrive at the advising office in the next hour?

$[$Hint $--$ the question asks just about arrivals, not an operational characteristic of the queueing model$]$
