It is computed that when a basketball player shoots a free throw, the odds in favor of his making it are 20 to 3 . Find the probability that when this basketball player shoots a free throw, he misses it. Out of every 100 free throws he attempts, on the average how many should he make? The probability that the player misses the free throw is (Type an integer or a simplified fraction.)

From 1975 through 2020, the mean annual gain of the Dow Jones Industrial Average was 653 . A random sample of 32 years is selected from this population. What is the probability that the mean gain for the sample was between 500 and 800 ? Assume \( \sigma=1541 \). The probability is (Round to four decimal places as needed.)
