7. (a) In a CPM network, the critical path includes five activities. Their durations are tabulated as follows: Duration (Days) Most Likely Time (Tm) Activity Optimistic Time (T) 2 5 A AB C D E Pessimistic Time (T) 7 14 8 2 21 4 8 6 2 2 7 10 Compute the following values: (i) The probability that the project will finish by the end of day 32 A (ii) The probability that the project will finish by the end of day 34 (iii) The probability that the project will finish before day 30 (iv) The probability that the project will finish on the 32nd day 7.
