In the above problem the arrival rate =0.5 per hour. Consider only the first server, S1 with an average T=3 hours. If this arrival was exponentially distributed, what number will take longer than 3 to complete processing at S1 ? Use the probability equation. Proportion taking longer than 3 hours to complete = \begin{tabular}{ll} & 0.0% \\ \hline \#N/A & \\ \hline \end{tabular} Probability(Totaltimeinprocess>t)=eTtD=eTt=EXP(t/T)wheretD=t=DuratoinPromised,T=averageprocessingtime
