Multiple Choice

A waiting-line system that meets the assumptions of M/M/S has λ = 5, μ = 4, and M = 2. For these values, P_o is approximately 0.23077, and L_s is approximately 2.05128. What is the average number of units waiting in the queue?

A) approximately 0.1603
B) approximately 0.4103
C) approximately 0.8013
D) approximately 1.0417
E) Cannot be calculated because λ is larger than μ.
