Given the information below, estimate the probability that the noncritical path B-F-G will take more than 20 weeks. Hint: Subtract from 1.0 the probability that B-F-G will take 20 weeks or less. Refer to the standard normal table

Activity	Expected Time (weeks)		Variance
A	4.0		0.75
B	6.0		0.69
C	4.0		0.25
D	12.0		1.78
E	7.0		2.10
F	8.5		2.55
G	5.0		0.69
