17. Given the following table, construct a network diagram, either AOA or AON. Times are in days. a. Determine the expected duration of the project. b. Compute the probability that the project will take at least 18 days. Path Activity Time Estimates Top A 4-5-6 B 7-8-10 C 3-5-9 Bottom D 7-8-11 E 2-3-4 F 1-4-6 6. Trucks are required to pass through a weighing station so they can be checked for weight violations. Trucks arrive at the station at the rate of 40 an hour between 7:00 pm. and 9:00 pm. Currently two inspectors are on duty during those hours, each of whom can inspect 25 trucks an hour. a. How many trucks would you expect to see at the weighing station, including those being inspected? b. If a truck was just arriving at the station, about how many minutes could the driver expect to be at the station? Page 820 What is the probability that both inspectors would be busy at the same time? P'P How many minutes, on average, would a truck that is not immediately inspected have to wait? FD What condition would exist if there was only one inspector? r": What is the maximum line length for a probability of .97
