Aserver operates with 80% utilization. the coefficient of variation for the service process is 0.5 and the coefficient of variation of the arrival process is 1. the average processing time is 3 minutes. what is the average time a customer spends in the system according to the single-server queue model?

10 minutes, 30 seconds

Step-by-step explanation:

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
