Q.2. As a part of her dinner party planning, Jeanie wants to see whether she can bake a rice-and-broccoli casserole. She knows that there are some uncertainties when it comes to cooking a new dish because some tasks might take less time than she imagines and some would take more time because there is always a likelihood of messing the sauce up and starting from scratch. Thus, she creates the following table to for the time (in minutes) she would take to create the casserole based upon her estimated optimistic, pessimistic, and most probable times based upon the steps in the recipe. Create the relevant project network and activity schedule (show work in your submission file in the last question of this problem set) and answer the questions given below.

					Most
			Immediate	Optimistic	Probable	Pessimistic
Activity	Description	Predecessor	time (a)	time (m)	time (b)
A	Soak rice		8	10	15
B	Cut up onions		3	5	7
C	Cut up broccoli		6	10	14
D	Cook rice	A	6	7	11
E	Make cream and cheese sauce	B	5	6	10
F	Soak broccoli in hot water	C	2	2	5
G	Mix sauce, rice, and broccoli	D, E, F	2	3	4
H	Bake in hot oven	G	28	30	35

1. The total time (in minutes) for Jeanie to finish the casserole is
2. What is the probability that Jeanie can complete the casserole in 55 minutes? % (write the answer in percent form with two decimal places)
3. The critical path is (write it out in the form of A-B-C-D-E... with the correct activities)
