The following three tasks form the entire critical path of the project network. The three estimates of each of these tasks are tabulated below. How long would the project take to complete expressed with an accuracy of one standard deviation?
Task Optimistic Most likely Pessimistic
A 15 25 47
B 12 22 35
C 16 27 32
A. 75.5
B. 75.5 +/- 7.08
C. 75.5 +/- 8.5
D. 75.5 +/- 2.83
Please share your answers with details and formula. I am struck up with finding how...
