consider a queeing system where there is one server with a processing capacitu of 35 customers per hour with exponentially distributed processing times. clients arrive at an average of 20 customers per hour with exponentially distributed inter-arrival times.whatis the probability of waiting in line and probability of finding a queue?. also what would be tbe performance measures L, q, Wq if there the arrival duplicates? if needed the number of servers should be increased from c=1 to c=2, if not needed the number of servers remain as c=1.
