Extracted text: Q4 telephone switch with 3 circuits (servers) is modeled as an M/M/C queuing system with respective call arrival and departure rates equal to 75 call/s and 100 call/s. If 47.196 is the probability that the switch is idle (has no calls), then the probability that customers have to wait before serving their call is equal to [Pr] 96. Report your answer as a percentage rounded to one digit after the decimal point.
