Together with your team, you applied three-point estimation on a Critical path which consists of two activities. The following duration ?

uncertainties are all calculated assuming a ±3sigma Confidence interval. The duration uncertainty-defined as pessimistic minus optimistic estimate-of the first activity is days; the second estimate has an uncertainty of days. Applying the PERT formula, what is the duration uncertainty of the entire path? A. No statement is possible from the information given. B. days C. days D. days
