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

If required, round your answers to two decimal places. Enter $"0"$ if your answer is zero.

Critical Path: B$-$E$-$H$-$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 $=$

weeks. If required, round your answer to two decimal places.
