- The first variation of the expected value formula is the EV of one event repeated several times (think about tossing a coin). In such a case, the EV can be found using the following formula: Where: 1. EV– the expected value 2. P(X)– the probability of the event 3. n– the number of the repetitions of the event However, in finance, many problems rela...

- To discover the expected worth or long term average,μ, simply multiply each value of the random variable by its likelihood and add the products. When evaluating the long-time period outcomes of statistical experiments, we often want to know the “average” consequence. This “lengthy-term average” is called the mean or expected value of the experiment...
