question 1 question 1 question 2 An activity on a PERT

question 2

An activity on a PERT network has these time estimates: optimistic = 2, most likely = unknown, and pessimistic = unknown. If variance = 4 and expected time = 6, what are the most likely and pessimistic estimates? 6.9 5, 14 5,12 8. 14 8,12 Contract requirements state that a project must be completed within 185 working days, or it will incur penalties for late completion. Analysis of the activity network reveals an estimated project time of 145 working days with a project variance of 400. What is the probability that the project will be completed after 149 working days and before the late-payment deadline? (Choose the nearest vale) near 1.0000, or almost certain 0.70 0.68 0.39 0.95
