Answer a:
Activity | Optimistic time-a | Expected completion time-m | Pessimistic time-b | Expected time= (a+4*m+ b)/6 | Variance, (sigma)^2= (b-a/6)^2 |
A | 4 | 6 | 8 | 6.00 | 0.44 |
B | 3 | 4 | 5 | 4.00 | 0.11 |
C | 2 | 3 | 4 | 3.00 | 0.11 |
D | 3 | 4 | 11 | 5.00 | 1.78 |
E | 1 | 3 | 5 | 3.00 | 0.44 |
F | 2 | 4 | 6 | 4.00 | 0.44 |
Answer b:
Answer c:
Paths | Duration | |
