Probability distribution expected value. A random variable is a variable that takes specic values with specic probabilities. In finance it indicates the anticipated value of an investment in the future. It is a mathematical description of a random phenomenon in terms of its sample space and the probabilities of events subsets of the sample space.

Right panel shows a probability density for a continuous random variable. Expected value expected arithmetic average when an experiment is repeated many times. Use the expected value formula to obtain.

Expected value and variance all probability distributions are characterized by an expected value mean and a variance standard deviation squared. For a discrete random variable rv with probability distribution function pxthe definition can also be written in the form mu sumxpx. In probability theory the expected value of a random variable denoted or is a generalization of the weighted average and is intuitively the arithmetic mean of a large number of independent realizations of the expected value is also known as the expectation mathematical expectation mean average or first momentexpected value is a key concept in economics finance and many other.

Also called the mean. What is the expected value ev. The expected value informs about what to expect in an experiment in the long run after many trials.

In statistics and probability analysis the expected value is. 8 the mean of a probability distribution mean the mean is a typical value used to represent the central location of a probability distribution. Mu is equal to the expected value of x is equal to the summation of k equals 1 to n x k times f of x k.

In probability theory and statistics a probability distribution is the mathematical function that gives the probabilities of occurrence of different possible outcomes for an experiment. Random variables distributions and expected value fall2001 professorpaulglasserman b6014. So mu here we use for the expected value not to be confused with mu that we previously used for the mean of a population.

The expected value ev is an anticipated value for an investment at some point in the future. So basically what the expected value is is the probability weighted average of all possible values. In a probability distribution the weighted average of possible values of a random variable with weights given by their respective theoretical probabilities is known as the expected value usually represented by ex.

Managerialstatistics 403urishall the idea of a random variable 1. The only possible values that we can have are 0 1 2 and 3. The random variable x is discrete and finite.

Expected value also known as ev expectation average or mean value is a long run average value of random variables. Expected value is a commonly used financial concept. It also indicates the probability weighted average of all possible values.
