Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty. The higher the probability of an event, the more likely it is that the event will occur. A simple example is the tossing of a fair (unbiased) coin. Since the coin is fair, the two outcomes are both equally probable; the probability of "heads" equals the probability of "tails"; and since no other outcomes are possible, the probability of either "heads" or "tails" is 1/2.
The Summer Olympic Games also known as the Games of the Olympiad, are a major international multi-sport event normally held once every four years. The Games were first held in 1896 in Athens, Greece, and were most recently held in 2016 in Rio de Janeiro, Brazil. The International Olympic Committee (IOC) organises the Games and oversees the host city's preparations. In each Olympic event, gold medals are awarded for first place, silver medals are awarded for second place, and bronze medals are awarded for third place; this tradition began in 1904. The Winter Olympic Games were created out of the success of the Summer Olympics.
Time is the indefinite continued progress of existence and events that occur in an apparently irreversible succession from the past, through the present, into the future. It is a component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in the conscious experience. Time is often referred to as a fourth dimension, along with three spatial dimensions.

The decathlon is contested mainly by male athletes, while female athletes typically compete in the heptathlon.

Killed in action (KIA) is a casualty classification generally used by militaries to describe the deaths of their own combatants at the hands of hostile forces. The United States Department of Defense, for example, says that those declared KIA need not have fired their weapons but have been killed due to hostile attack. KIAs include those killed by friendly fire in the midst of combat, but not from incidents such as accidental vehicle crashes, murder and other non-hostile events or terrorism. KIA can be applied both to front-line combat troops and to naval, air and support troops. Someone who is killed in action during a particular event is denoted with a † (dagger) beside their name to signify their death in that event or events.
