Answer correctly

Consider the same urgent care center with $4$ doctors where the average arrival rate for each doctor is $24$ patients per hour and the average service time of

each patient is $2$ minutes. Both inter$-$arrival times and service times have a coefficient of variation equal to one. But now,

the doctors are pooled so that a doctor can serve any patient. After pooling, what is the average number of patients in the clinic $($including those waiting in

line to see a doctor as well as those who are seeing a doctor$)?$ Recall there is only one common queue after pooling and round your answer to two decimal

points.
