Assume that four adults are randomly selected without replacment from the 258,343,280 adults in the United States. Also, assume that 12.5% of adults in the United States use drugs. Find the probability that four selected adults all use drugs. Note: You will need to round to six decimal places.

As Prof. A. M. Goon said
"Suppose there is a finite population of size N that contains exactly K objects that has a specified feature. A random sample of size n has been drawn from this population without replacement, wherein each draw is either a success or a failure. Then the probability distribution of the number of objects in the sample with that feature, called success, is said to follow Hypergeometric distribution.
Let us assume X be a random variable denoting the number of success.
Then , N, K and n being the parameters of the hypergeometric distribution.
The probability mass function of X is given by,
