The distribution of the scores on a certain exam is N(30,10), which means that the exam scores are Normally distributed with a mean of 30 and standard deviation of 10. What is the probability that a randomly selected score will be greater than 40? Using the Empirical Rule, the probability that a randomly selected score will be greater than 40 is about ____%.
