Randomness is the lack of pattern or predictability in events. A random sequence of events, symbols or steps has no order and does not follow an intelligible pattern or combination. Individual random events are by definition unpredictable, but in many cases the frequency of different outcomes over a large number of events (or "trials") is predictable. For example, when throwing two dice, the outcome of any particular roll is unpredictable, but a sum of 7 will occur twice as often as 4. In this view, randomness is a measure of uncertainty of an outcome, rather than haphazardness, and applies to concepts of chance, probability, and information entropy.
The fields of mathematics, probability, and statistics use formal definitions of randomness. In statistics, a random variable is an assignment of a numerical value to each possible outcome of an event space. This association facilitates the identification and the calculation of probabilities of the events. Random variables can appear in random sequences. A random process is a sequence of random variables whose outcomes do not follow a deterministic pattern, but follow an evolution described by probability distributions. These and other constructs are extremely useful in probability theory and the various applications of randomness.
A role model is a person whose behavior, example, or success is or can be emulated by others, especially by younger people. The term "role model" is credited to sociologist Robert K. Merton, who coined the phrase during his career. Merton hypothesized that individuals compare themselves with reference groups of people who occupy the social role to which the individual aspires. An example being the way fans (oftentimes youth) will idolize and imitate professional athletes or entertainment artists.
In the second half of the twentieth century, U.S. advocates for workplace equity popularized the term and concept of role models as part of a larger social capital lexicon—which also includes terms such as glass ceiling, networking, mentoring, and gatekeeper—serving to identify and address the problems barring non-dominant groups from professional success. Mainstream business literature subsequently adopted the terms and concepts, promoting them as pathways to success for all career climbers. In 1970 these terms were not in the general American vocabulary; by the mid-1990s they had become part of everyday speech. Although the term "role model" has been criticized more recently as "outdated", the term and its associated responsibility remains prominent in the public consciousness as a commonly used phrase, and a "powerful presence" in the entertainment industry and media.
