The weights of a certain brand of candies are normally distributed with a mean weight of 0.8589 g and a standard deviation of 0.0518 g. A sample of these candies came from a package containing 470 candies, and the package label stated that the net weight is 401.3 g.(If every package has 470 candies, the mean weight of the candies must exceed 401.3470=0.8539 g for the net contents to weigh at least 401.3 g.)

a. If 1 candy is randomlyselected, find the probability that it weighs more than 0.8539 g.

The probability is
