    A project has been defined to contain the following activities, along with their time estimates for completion. Carry three decimals in your calculations and answer the following questions:

    Activity Time Estimates (weeks) Immediate Predecessors
    a m b
    A 2 5 6 -
    B 1 5 11 -
    C 4 6 10 A
    D 2 2 2 B
    E 1 2 9 A
    F 2 4 5 C,D
    G 3 8 11 C,E
    H 1 2 4 F,G

    a. What is the expected duration of activity H?
    b. What is the variance of activity H time?
    c. Using the expected activity durations, which activities form the critical path?
    d. What is the probability of completing the critical path found in (C) above in 22 weeks or less?
