Question:

At a train station, there are 7 ticket vending machines. Customers form a single waiting line to buy tickets from one of the machines. It is observed that the interarrival time is exponentially distributed with its mean equal to 3.0 minutes. On average, it takes a customer 6 minutes to buy a ticket, with a standard deviation of the time estimated as 1 minutes.

On average, what is the total number of customers at the ticket vending site (including those waiting in the line and those buying tickets)?
