# Determine expected value

The formula for the expected value is relatively easy to compute and involves several multiplications and additions. In this video, I show the formula of expected value, and compute the expected value of a game. The final. Expected Value for a Discrete Random Variable. E(X)=\sum x_i p_i. x_i= value of the i th outcome p_i = probability of the i th outcome. According to this formula.

### Determine expected value - Sie

Calculate the sum of the products. Assume the following situation: Given a large number of repeated trials, the average of the results will be approximately equal to the expected value Expected value: Let be an absolutely continuous random variable. To use this calculator, a user simply enters in the value of each event or x and the probability of each event or x occurring. The probability P of getting a question right if you guess: Let be an absolutely continuous random variable with uniform distribution on the interval. Your explanations on here are clear cut and easy to follow. Expected value EV is a concept employed in statistics to help decide how beneficial or harmful an action might be. What is the 'Expected Value' The expected value EV is an anticipated value for a given investment. In some cases, you may need to assign a value to some or all possible outcomes. The expected value is the value which you would expect to receive for a future average or mean in advance.
