Find the critical path and the project completion time for the following list of activities. Calculate the probabilities of completing the following project in: a) 13 days or more b) 11 days or less c) Between 12 and 14 days Activity Immediate Predecessor Optimistic Duration Most Probable Duration Pessimistic Duration A - 1 3 5 B - 2 4 6 C A,B 2 4 5 D A,B 3 5 7 E C,D 1 2 10

I do not understand how you are coming up with the answers. I understand the concept. I know how the teacher explained it but the examples to the problems are not making sense. they all have different answers.
