WebMar 10, 2024 · Expected Value: The expected value (EV) is an anticipated value for a given investment. In statistics and probability analysis, the EV is calculated by multiplying each of the possible outcomes by ... WebOct 13, 2015 · It appears that the expected value is E [ X] = ∫ − ∞ ∞ x f ( x) d x where f ( x) is the probability density function of X. Suppose the probability density function of X is f ( x) = 1 2 π e − x 2 2 which is the density of the standard normal distribution. So, I would first plug in the PDF and get E [ X] = ∫ − ∞ ∞ x 1 2 π e − x 2 2 d x

WebA derivative is a financial contract whose value is dependent upon or derived from one or more underlying assets. While a derivative can be bought and sold, it has no value without the underlying asset. ... If the asset doesn’t decline as expected, the derivative can be sold for a profit or go unused if it’s an option. As a result, the ... WebDerivatives of all orders exist at t = 0. It is okay to interchange differentiation and summation. That said, we can now work on the gory details of the proof: Proof: Evaluating for mean and variance Watch on Example 9-2 Use the moment-generating function for a binomial random variable X: M ( t) = [ ( 1 − p) + p e t] n
