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. The average number of units waiting in the queue

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