A Bernoulli distribution is useful because it can be used to approximate the outcomes of an experiment (such as tossing a coin) as a range of percentages. It represents a "yes or no" type experiment. If the experiment succeeds, then it is given the value 1. If the experiment does not succeed, it is given value 0. This can be used, for example, in tossing a coin, where "1" means it lands on "heads", and "0" means it lands on "tails" (or the other way around).
This distribution has only one parameter, the probability of a success ("p"). In fact, Bernoulli distribution is the binomial distribution with "n"=1, and "n" independent and identically distributed Bernoulli distributions also give rise to binomial distribution.

Adams–Onís Treaty
The Adams-Onís Treaty (also called the Florida treaty) was a treaty between Spain and the United States of America in 1819. This treaty gave the state of Florida to the United States. It settled a standing border dispute between the two countries. It established the U.S- Mexican border.
The treaty was considered a triumph of American diplomacy. It came at a time of increasing difficulties related to Spain's territorial boundaries in North America. This was with both the United States and Great Britain following the American Revolution. There were also tensions during the Latin American Wars of Independence. Florida had become a problem for Spain. It could not afford to send settlers or garrisons.
The treaty was signed in Washington, DC on February 22, 1819. It was ratified in Madrid, Spain on October 24, 1820. The treaty actually went into effect on February 22, 1821. Madrid decided to cede the territory of Florida to the United States. This was in exchange for settling the boundary dispute along the Sabine River in Texas. The treaty established the boundary of U.S. territory. It recognized the claims of the United States through the Rocky Mountains and west to the Pacific Ocean. In exchange the U.S. paid residents' claims against the Spanish government up to a total of $5,000,000. The United States also gave up its claims on parts of Spanish Texas west of the Sabine River and other Spanish areas, under the agreements in the Louisiana Purchase. Adams-Onis was a key event in determining the U.S.-Mexico border.
