Calculate probabilityNow that you have the project teand the project standard deviation, answer the following questions:
-What is the probability of achieving your tedate?
-What date corresponds to a 95% probability?
-If the airport requests to reduce your tedate by 1 week, what is the probability of achievement? What is the probability of achieving a 2-week reduction?
