A waiting-line system that meets the assumptions of M/M/S has λ = 5,μ = 4,and M = 2.For these values,Po is approximately 0.23077 and Ls is approximately 2.05128.The average time a unit spends in this system
A)is approximately 0.1603.
B)is approximately 0.2083.
C)is approximately 0.4103.
D)is approximately 0.8013.
E)cannot be calculated because λ is larger than μ.

The average time a unit spends in the system (Ws) is calculated as Ls/λ. Given Ls = 2.05128 and λ = 5, Ws = 2.05128 / 5 = 0.410256, which is approximately 0.4103.
