1. A local project being analyzed by PERT has 42 activities, 13 of which are on the critical path. If the estimated time along the critical path is 105 days with a project variance of 25, what is the probability that the project will be completed in 95 days or more? -0.40000 0.02275 0.34444 0.97725 4.20000

2. Which of these statements regarding time-cost tradeoffs in CPM networks is TRUE? Crashing is possible even if there are multiple critical paths. Crashing a project often reduces the length of long-duration, but noncritical, activities. Activities not on the critical path can never be on the critical path, even after crashing. The crash time always exceeds the normal time
