Consider a project that has been modeled as follows:

Activity Pre$-$acti Optimistic$($wks$)$ Most Likely Pessimistic

A None $91521$

B None $132123$

C A $6918$

D B $233547$

E A$,$D $192627$

F C $232941$

G D$,$ E $142026$

H E$,$ F$,$ G $258$

Determine project's expected completion time and its critical path.

Answer: Critical Path$\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$

Expected completion time$\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$

$$

What is the probability that the project will complete more than $27$ weeks?
