Please help by using excel, typed or text. I do not understand most hand writing.

PERT/CPM During the Corona-Quarantine, Emily decides to teach her kids how to bake cookies. She wants to take the opportunity to practice her own PERT/(3PM project management skills as well. So, she lists out the activities that are required to bake two batches of cookies including the predecessors (if any) for each activity and the optimistic, most probable, and pessimistic time (in minutes) it takes to complete each activity; especially since she knows that everything can take longer when working with children. Some of the timings are xed (e.g. baking or cooling times) so you will see that she has the same values for the optimistic, most probable, and pessimistic times. Create a network diagram and an activity Schedule in your Excel/Word/PDF le and answer the questions given below the table.

What is the expected number of minutes it would take for Emily to complete her project? minutes 2. The activity with lowest slack is 3. The probability of completing both batches of cookies in 44 minutes is %
