EXPECTED VALUE Meaning and
Definition
-
The term "expected value" refers to a concept commonly used in probability theory and statistics to calculate the average result or outcome of a random variable. It represents the anticipated outcome of an experiment or event, taking into account the probabilities associated with each possible outcome.
Mathematically, the expected value is calculated by multiplying each possible outcome of a random variable by its probability, and summing all of these products. It acts as a measure of central tendency that provides an estimate of what value is likely to occur on average over many repetitions of the same experiment.
The expected value is a crucial tool as it allows decision-makers to gain insights on the potential outcomes of a random process, ultimately aiding in making rational and informed decisions. By determining the expected value, individuals can assess the potential risks and rewards associated with different strategies and select the most advantageous one.
Additionally, the expected value helps to evaluate the fairness and profitability of certain games, financial investments, or insurance policies. For instance, in gambling, it can assist in understanding the average return or losses expected from a particular bet. In finance, expected value calculations can guide investors in assessing the potential returns of investments, considering the associated probabilities.
Overall, the expected value is a fundamental concept that brings together the probabilities and possible outcomes of a random variable, enabling individuals to make informed decisions based on the most likely or average result of an experiment.

Etymology of EXPECTED VALUE
The term "expected value" has its roots in the field of probability and statistics. The word "expected" comes from the Latin word "expectatus", which means "anticipated" or "looked for". "Value" refers to the assigned numerical worth or significance of something. In the context of probability and statistics, the expected value represents the anticipated average outcome or return of a random variable or uncertain event. The concept was first introduced by mathematicians around the 17th century and has since become a fundamental concept in probability theory and decision making.
