Lottery In Florida’s Play 4 lottery game, four digits between 0 and 9 inclusive are randomly selected each day. We normally expect that each of the 10 different digits will occur about 1/10 of the time, and an analysis of last year’s results shows that this did happen. Because the results are what we normally expect, is it correct to say that the distribution of selected digits is a normal distribution?

Bird wingspans The wingspans of the females of a certain species of bird of prey form a normal distribution with mean 168-75 cm and standard deviation 6-5 cm. The wingspans of the males of the species are normally distributed with mean 162-5 cm and standard deviation 6 cm. What is the probability that, if a male and female are taken at random, the male has a larger wingspan than the female?

Aunt Maize Corn-atorium processes stalks of corn into cobs of corn and packages them in bundles for grocery stores across the region. The distribution of corn in each bundle is approximately normal, with mean of 100 cobs of corn in each bundle, and a standard deviation of 10. Determine the probability that a randomly selected bundle of corn has fewer than 107 cobs of corn.
