Explanation Formula used: The sum of degrees in a graph ∑ v ∈ T d ( v ) = 2 n − 2 Here, v represents the vertex, n represents the number of vertices. Description: Consider that d 1 , d 2 , … , d n are the positive integers. It is known that the sum of degrees of all vertices in a tree is given by the following relation. ∑ i = 1 n d i = 2 n − 2 Consider that ∑ i = 1 n

In a small office, there are m = 5 typists who need to use a single typewriter to complete their reports. Assume the time each typist takes to prepare a report follows an exponential distribution with an average of 20 minutes per preparation (A = 3 reports/hour), and the service time for the typewriter to type out a report also follows an exponential distribution, averaging 30 minutes to complete a report (μ 2 reports/hour). Given that the number of typists is finite and all typists = share one typewriter, they will form a waiting queue. (1). Describe this queuing system and explain how it fits the characteristics of the M/M/1/∞0/m model. (2). Calculate the probability that any typist is using the typewriter at steady-state. (3). Calculate the average number of typists waiting in the queue at steady-state. (4). Considering the need to reduce waiting time, if an additional typewriter is introduced (turning into a two-server system, or M/M/2/∞0/m model), analyze the expected impact,…
