O5: Coasider the following table summarizing the details of a project: Activity Predecessorts) Duration (weeks) Most Ukely time Optimistic time Pessimistic time 10 4 2 14 D. A 3 B.C 4 D 2 2 E.G 6 8 10 (a) Construct the project network (b) Find the expected duration and variance of each activity. (c) Find the critical patb and the expected project completion time. (d) What is the probability of completing the project on or before 20 weeks'? (e) If the probability of completing the project is 0.85, find the expected project completion time.

10. Assume that the duration of some activities is not known with certainty. The estimates of these activities are shown below. Activity A C D G H Optimistic Q 8 3 10 13 8 Most Likely 10 5 12 15 10 POM a. What is the project's expected completion time and its variance? b. What is the probability that the project will be completed in 61 days or more? c. What is the probability that the project will be completed in no more than 54 days? c. If the company wants a 94% probability of completing the project on time, state the latest time each activity should have started and completed. Pessimistic 5+ 12 7 14 17 12

4. Using the following information, perform the following: a. Network diagram b. Determine which activities are on the critical path c. Compute the length of the critical path Activity Estimated time (days) 1-2 5 2-3 6 2-4 4. 3-6 10 6-7 4-5 5 4-7 16 5-7 10 Answer: 3.

Can u solve question according to table
