distribution that resembles the negative exponential distribution. ) The utilization rate of this service system = (round your response to two decimal places). ) The average downtime for a broken machine = days (round your response to two decimal places). ) The average number of machines waiting to receive service at any given time = machines (round your response to three decimal places). d) The probability that there is more than one machine that is in the system = (round your response to three decimal places). The probability that there are more than two machines that are in the system = (round your response to three decimal places). The probability that there are more than three machines that are in the system = (round your response to three decimal places). The probability that there are more than four machines that are in the system = (round your response to three decimal places)
