Develop a network drawing for Towns Construction and determine the critical path. How long is the project expected to take? 2. What is the probability of finishing in 270 days? 3. (Enrichment) if it is necessary to crash to 250 or 240 days, how would Towns do so, and at what costs? As noted in the case, assume that optimistic time estimates can be used as crash times
