#1. I believe it is C. Since it is calculating which each one of these.
#2. I believe it is C also. Since calclulating the pessimistic and optimistic activity times will give you the activity time within the equation you are trying to solve. But for some reason I am second guessing myself. These questions are on a practice test. But we are aloud to use any information we can on our final (which is 4 hours long). So I want to make sure I have everything correct in case one of these questions were to actually come up. Thanks for the help. |
