Experience 5 - The Binomial Distribution

The Binomial Distribution



The binomial distribution is the most common discrete distribution used in elementary statistics. Exploring this standard distribution in detail will give us a better idea of what discrete probability distributions are all about as well as provide a system for determining the likelihood for obtaining a given sample proportion. As we will see, many questions can be answered using the binomial distribution, such as “What is the chance that at least one person in a random sample of 10 will vote a certain way”. Your ability to plan for future events and make wise decisions will be greatly aided by the techniques that follow.
