In the study of fingerprints, an important quantitative characteristic is the total ridge count for the ten fingers of an individual. Suppose that the total ridge counts of individuals in a certain population are approximately normally distributed with a mean of 140 and a standard deviation of 50. Find the probability that an individual picked at random from this population will have a ridge count of: (Explain your answer in each bullet)200 or moreLess than 100Between 100 and 200Between 200 and 250In a population of 10,000 people, how many would you expect to have a ridge count of 200 or more?
