Sampling from the Cauchy distribution and averaging gets you nowhere — one sample has the same distribution as the average of samples! Here we see that the expected value of our random variable is expressed as an integral. By contrast, the variance is a measure of dispersion of the possible values of the random variable around the expected value. The interpretation is that if you play many times, the average outcome is losing 17 cents per play. The idea of the expected value originated in the middle of the 17th century from the study of the so-called problem of points , which seeks to divide the stakes in a fair way between two players who have to end their game before it's properly finished. The more examples the better. If you have a discrete random variable , read this other article instead: The expected value of X is usually written as E X or m. If one considers the joint probability density function of X and Y , say j x , y , then the expectation of XY is. In particular, Huygens writes: The expected value of a random variable is just the mean of the random variable.
