The activity time estimates $($in weeks$)$ are as follows:

A$.$ Develop an activity schedule for this project and identify the critical path activities.

If required, round your answers to two decimal places. If your answer is zero enter $"0^n.$

Critical Path:

A$-$D$-$I OR B$-$C$-$D$-$I OR B$-$E$-$G$-$I OR B$-$E$-$H$-$J OR B$-$F$-$J

B$.$ What is the probability that the project will be completed so that Landon Corporation may introduce

the new product within $25$ weeks? Within $30$ weeks?

Expected project completion time $=$
