ed with probability, the expected value simply factors in the relative chances of each event occurring, in order to determine the overall result. The more probable outcomes will have a greater weighting in the overall calculation. <span>For a random variable X, the expected value of X is denoted E(X). E(X) = P(x 1 ) x 1 + P(x 2 ) x 2 + ... + P(x n ) x n In investment analysis, forecasts are frequently made using expected value, for example,
