As a casual observer, you noticed that on average there will be a student entering the BCC every 10 minutes, with a standard deviation of 3 minutes. There is only one staff, Mr. B, at the front desk. On average, it takes him 6 minutes to serve every arrival, with a standard deviation of 4 minutes. Assuming student arrival rate follows a general distribution and service time follows an general distribution.

Now assuming that the office hired one more staff to help Mr. B out. Both the inter-arrival time and service time are generally distributed and students only form one queue. Additionally, assume the extra staff works exactly the same (in speed and variability) as Mr.B. All other numbers from the previous scenario still apply.

Q1. Under this new scenario where there are two staff working, on average, how many students in total would you expect to see at BCC? Round answer to two decimal places.

Q2. Under this new scenario, what would be the average total time ( in minutes) a student should expect to spend at BCC? Round answer to two decimal places.
