B) If the project is due to be completed in 21 days, using Table 4 , what is the probability that the project will be completed on or before the due date? C) Using both Table 3 and Table 4. What is the sequence that activities to be crashed to achieve the least cost objective? D) Following pt. C), assume that the pessimistic times for all activities you just crashed in Question C) are one week more than the most-likely times after crashing. What is the probability that the project will be completed on or before the due date?)
