Can you figure out Std DEV. I cant understand how to get it.. Consider the following tasks with three different types of durations (optimistic a, most likely m, pessimistic b). For each task, find the expected duration, variance and standard deviation. Then draw the AON diagram; find the critical path and the expected project completion time. Then compute the probability of completing the project in (i) 21 days; (ii) 22 days; and (iii) 25 days.
| Task | a | m | b | Expected | Variance | Std Dev. |
| A | 6.5 | 7.5 | 14.5 | |||
| B | 8.5 | 10.5 | 12.5 | |||
| C | 2.5 | 3.5 | 4.5 | |||
| D | 6.5 | 7.5 | 8.5 | |||
| E | 5.5 | 5.5 | 9.5 | |||
| F | 5.5 | 7.5 | 9.5 | |||
| G | 4.5 | 6.5 | 8.5 | |||
