Let $x$ be the number of successes observed in a sample of $n=5$ items selected from a population of $N=10 .$ Suppose that of the $N=10$ items, $M=6$ are considered "successes." Find the probabilities in Exercises $11-13 .$
The probability of observing no successes.

Key Concepts

Hypergeometric Distribution

The hypergeometric distribution models the probability of drawing a specific number of successes in a sample taken without replacement from a finite population. It is applicable when the population is divided into two categories, such as successes and failures, and the probability changes as items are drawn without replacement.

Combinatorial Counting

Combinatorial counting uses techniques such as binomial coefficients to count the number of ways that events can occur. In the context of the hypergeometric distribution, it calculates the number of ways to select a specified number of successes and failures from the population, which is essential for determining probabilities.

Sampling Without Replacement

Sampling without replacement is a method where each selected item is not returned to the population before the next draw. This impacts the probability computations because the composition of the population changes with each draw, which is a key aspect of problems modeled by the hypergeometric distribution.
