In this video, I show the formula of expected value, and compute the expected value of a game. The final. The expected value (or mean) of X, where X is a discrete random variable, is a weighted average of the possible values that X can take, each value being. Anticipated value for a given investment. In statistics and probability analysis, expected value is calculated by multiplying each of the possible outcomes by the. what is expected value By calculating expected values, investors can choose the scenario most likely to give them their desired outcome. When is a discrete random vector and is its joint probability function, then When is an absolutely continuous random vector and is its joint density function. Thus, over time you should expect to lose money. The interpretation is that if you play many times, the super mario bros gratis outcome is losing 17 cents per play. Multiply 1 by 2 to get: It says that, if you need to compute the expected value ofyou do not need to know the support of and its distribution function:
