Expected Value: E(X)

This relationship can be used to translate properties of expected values into properties of probabilities, e. The moments of some random variables can be used to specify their distributions, via their moment generating functions.

To empirically estimate the expected value of a random variable, one repeatedly measures observations of the variable and computes the arithmetic mean of the results.

If the expected value exists, this procedure estimates the true expected value in an unbiased manner and has the property of minimizing the sum of the squares of the residuals the sum of the squared differences between the observations and the estimate.

The law of large numbers demonstrates under fairly mild conditions that, as the size of the sample gets larger, the variance of this estimate gets smaller.

This property is often exploited in a wide variety of applications, including general problems of statistical estimation and machine learning , to estimate probabilistic quantities of interest via Monte Carlo methods , since most quantities of interest can be written in terms of expectation, e.

In classical mechanics , the center of mass is an analogous concept to expectation. For example, suppose X is a discrete random variable with values x i and corresponding probabilities p i.

Now consider a weightless rod on which are placed weights, at locations x i along the rod and having masses p i whose sum is one.

The point at which the rod balances is E[ X ]. Expected values can also be used to compute the variance , by means of the computational formula for the variance.

A very important application of the expectation value is in the field of quantum mechanics. Thus, one cannot interchange limits and expectation, without additional conditions on the random variables.

A number of convergence results specify exact conditions which allow one to interchange limits and expectations, as specified below.

There are a number of inequalities involving the expected values of functions of random variables. The following list includes some of the more basic ones.

There are two service line. The random variables X and Y are the proportions of time that line 1 and line 2 are in use respectively. The joint probability density function for X, Y is given by.

I have not checked all your calculations but if the rv's are not independent as it you correctly calculated the covariance can be negative, positive or zero.
