The diameter of an electric cable is normally distributed, with a mean of 0.7 inch and a standard deviation of 0.02 inch. What is the probability that the diameter will exceed 0.72 inch? (Round answer to three decimal places.)

The z-score is x-mean/ Standard Deviation

=( 0.72 -0.7)/0.02

=1

P(z>1) = 1-0.841 = 0.159
