Simple random sampling uses a sample of size n from a population of size N to obtain data that can be used to make inferencesabout the characteristics of a population. Suppose that, from a population of 40 bank accounts, we want to take a random sample ofseven accounts in order to learn about the population. How many different random samples of seven accounts are possible?

Here population size N = 40 Sample size n = 7
