a. The network diagram for a project is shown in the accompanying figure, with three time estimates for each activity. Activity times are in months. Do the following: Compute the expected time for each activity and the expected duration for each path; b. Identify the critical path; Compute the variance for each activity and the variance for each path; d. Find the probability that the project will be completed within 17 months of its start; C. e. f. 17206 Project Management QUESTION 2 Find the probability that the project will take longer than 18 months ~ 2%; Can the paths be considered independent? Why? Determine the probability that the project will be completed within 15 months of its start; What is the probability that the project will not be completed within 15 months of its start? h. 2-3-4 Opt.
