A project has four activities (A, B, C, and D) that must be performed sequentially. The probability distributions for the time required to complete each of the activities are as follows:
Activity |
Activity Time (weeks) |
Probability |

A | 5 | 0.32 | ||
6 | 0.39 | |||
7 | 0.27 | |||
8 | 0.02 | |||
B | 4 | 0.18 | ||
6 | 0.51 | |||

13 | 0.15 | |||
15 | 0.03 | |||
D | 10 | 0.61 | ||
12 | 0.39 | |||
