SUMMARY
The discussion focuses on solving an M/M/1 queuing theory problem involving a single employee serving customers. Customers arrive at a rate of 4 per hour, while the service rate is 5 per hour. The probability of exactly 4 customers arriving in one hour is calculated using the Poisson distribution, yielding a result of approximately 0.183. Additionally, the average time per customer is determined to be 12 minutes, and the probability that the cashier is idle is derived from the system's utilization rate.
