9. A small power system is monitored through 7 measurements whose errors are independently distributed according to a Normal distribu- tion with zero mean and a variance as given below for each measure- ment: Measurement, i 1 6.4010 234567 5 9.0010-6 1.6010-5 4.9010-6 1.0010-6 1.4410-6 2.5010-5 What is the probability that the absolute value of the error of at least one of the measurements will be greater than 0.01?
