Statistics, the science of collecting, analyzing, presenting, and interpreting data. Currently the need to turn the large amounts of data available in many applied fields into useful information has stimulated both theoretical and practical developments in statistics.
Probability and statistics, the branches of mathematics concerned with the laws governing random events, including the collection, analysis, interpretation, and display of numerical data. Learn more about the history of probability and statistics in this article.
Statistics is a branch of mathematics. It involves gathering information, summarizing it, and deciding what it means. The numbers that result from this work are also called statistics. They can help to predict such things as the weather and how sports teams will perform.
The Normandy Invasion, also called Operation Overlord or D-Day, was the Allied invasion of western Europe during World War II, which was launched on June 6, 1944 (the most celebrated D-Day of the war), with the simultaneous landing of U.S., British, and Canadian forces on five separate beachheads in Normandy, France.

Some solutions to water scarcity include conserving and valuing water, protecting and restoring freshwater and wetland ecosystems, investing in water infrastructure and technology, and addressing global warming. Learn about water on Earth and the dangers of water scarcity.
Probability theory, a branch of mathematics concerned with the analysis of random phenomena. The outcome of a random event cannot be determined before it occurs, but it may be any one of several possible outcomes. The actual outcome is considered to be determined by chance.
