(a) Draw the PERT network diagram for the project, labeling all activities and times. (b) Perform a forward pass and backward pass through the network to determine the critical path, the expected duration of the project, and the slack time for each activity. (c) What is the probability that the project will be completed in 17 days? (d) Allowing for lost days due to snow emergencies, what is the probability that the project will be completed in 15 days?
