What is Expectation of random variables in Statistics?
In probability theory, the expected value (also called expectation, expectancy, mathematical expectation, mean, average, or first moment) is a generalization of the weighted average. Informally, the expected value is the arithmetic mean of a large number of independently selected outcomes of a random variable.
The expected value of a random variable with a finite number of outcomes is a weighted average of all possible outcomes. In the case of a continuum of possible outcomes, the expectation is defined by integration. In the axiomatic foundation for probability provided by measure theory, the expectation is given by Lebesgue integration.
How to Calculate Expectation of Sum of Random Variables?
Expectation of Sum of Random Variables calculator uses Expectation of Sum of Random Variables = Expectation of Random Variable X+Expectation of Random Variable Y to calculate the Expectation of Sum of Random Variables, Expectation of Sum of Random Variables formula is defined as the average value or mean of the sum of two or more random variables. Expectation of Sum of Random Variables is denoted by E(X+Y) symbol.
