customers will wait only if NO customers are waiting. Assume that service times are exponentially distributed and
that the calling population is infinite. (a) VWhat is the queuing model? (b) To the nearest third decimal place, what is
the expected total time in steady state that a customer spends at the stand?
O (M/M/2): (GD/2/infınity), 18.333 minutes
O (M/G/2): (GD/infinity/infinity), 0.467 hours
none of the other choices
O (M/M/2) : (GD/3/infinity), 0.233 hours
