Question (89)

a) 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.

b) What is the probability that the project will be completed one week or more before the expected completion time?

c) What is the probability that the project will be completed two weeks or more before the expected completion time?
