| F | 2 | 4 | 7 | 4.166667 | 0.833333 | 0.694444 |
| G | 6 | 9 | 14 | 9.333333 | 1.333333 | 1.777778 |
| H | 1 | 2 | 4 | 2.166667 | 0.5 | 0.25 |
The possible paths are
ABEH with duration 17.99
ABDFH with duration 28.98
ACDFH with duration 29.98
ACGH with duration 22.49
The critical path is ACDFH with duration 29.98.
Variance of the CP =7,7221
SD of the CP = (7721)^0.5 =2.778
Probability that the project will be completed within 30 days
z = 30-29.98 /2.778 =0.0071
which gives a probability of 50%
Prob. of completing in 35 days
z = 35-29.98 /2.778 =1.807
which gives a probability of 0.9645
Note : As per Chegg policies I can answer the first four questions only. Inconvenience is regretted.
