QUESTION 1 2 points Saved A project has 22 activities. Each activity has optimistic, most ikely, and pessimistic activity times. We used expected time of each activity and found that the critical path has 10 activities. The total time along the critical path is 86 days and the variance of the critical path is 41. Write down the probability that the project will be completed in 97 days or less. Give your answer to four decimal places. QUESTION 2 1 points Saved An activity of a project has three time estimates. Its optimistic time is 29, most likely time is 36, and pessimistic time is 44. Write down the expected time of this activity. Give your answer to three decimal places. QUESTION 3 2 points Saved A contractor has accepted a project which has 22 activities. Each activity has optimistic, most ikely, and pessimistic activity times. We used expected time of each activity and found that the critical path has 11 activities. The total time along the critical path is 107 days and the variance of the critical path is 20. Contract requirements state that the project must be completed within 115 working days, or it will incur penalties for late completion. Write down the probability that the contract will pay penalty. Give your answer to four decimal places. QUESTION 4 1 points Saved An activity of a project has three time estimates. Its optimistic time is 40, most likely time is 48, and pessimistic time is 57. Write down the variance of the activity time of this activity. Give your answer to three decimal places
