Answer:
B. 6.96 projects
Explanation:
Base on the scenario been described in the question. We use the following method to get the answer
We have number of Servers as: m = 5
Inter-arrival time: a = 4.8 hrs
Service Time: p = 19.2
CVa = 1.25
CVp = 1
Utilization: u = 0.8
Expected waiting time: = 14.1951 hrs
Number of projects being programmed: 4
Number of projects waiting to be programmed = 2.9573
Now, total Number of uncompleted given projects at any given time = 6.9573
