A set of conditions that underlie the M/M/1 queue model, including that arrivals occur according to a Poisson process, service times have an exponential distribution, there is a single server, and the queue has infinite capacity.

Average Number

A statistical measure representing the central or typical value in a set of numbers, often calculated as the sum of all numbers divided by the count of numbers.

μ

The symbol commonly used to represent the mean or average in statistics and mathematics.
