Since there are two postal clerks, the system can be modeled as M/M/2. The arrival rate follows a Poisson distribution, service time follows an exponential distribution, and there are two servers. The letter D refers to a Deterministic service time, which is not the case here. The letter 1 refers to only one server, which is not the case here.
