Wine Spectator rates the wines on a point scale of 0 to 100. It can be inferred from the many ratings in the magazine that the average rating is 87 and the standard deviation is 3 points. Wine rating seems to follow the normal distribution. On May 15, 2020, the issue of the magazine, the burgundy Domaine des Perdrix received a rating of 89. What is the probability that a randomly chosen wine will score this high or higher?
