For a given activity,

Optimistic time= 17 days, Most likely time= 29 days and Pessimistic time= 47 days

Calculate

a. Weighted average activity time and variance

b. If the scheduled duration is 60 days, weighted average activity time is 64 days, and the variance is 36 days. What is the probability completing the project by time period 60 days
