Question

The passengers who want to check in with an agent walk in every 5 minutes (with a standard deviation of 5 minutes). There are 5 self-service counters installed, while there are two agents. A typical check-in process takes 4 minutes (with a standard deviation of 4 minutes), regardless of whether an agent or a self-service counter.
