Simple random sampling uses a sample of size  from a population of size  to obtain data that can be used to make inferences about the characteristics of a population. Suppose that, from a population of 75 bank accounts, we want to take a random sample of five accounts in order to learn about the population. How many different random samples of five accounts are possible?
