The activity network for the Largesse Hydro Project is shown below:

The following table gives the baseline cost estimate $($BCE$)$ and baseline time estimates $($BTE$),$

the cost and time estimates to correct for failure, and the likelihood of failure for each work

package $($or WBS element$)$:

a$.$ Determine the risk time and risk cost for all the WBS elements of the project.

b$.$ What is the project's expected cost $($EC$)$ and expected time $($ET$)?$
