This means that over the long run, you should expect to lose on average about 33 cents each time you play this game. Final result: Calculate Probability. I provided an example below from an Excel spreadsheet I drafted. Excel has a built-in formula to calculate probability through the PROB function. The first variation of the expected value formula is the EV of one event repeated several times (think about tossing a coin). The fourth column of this table will provide the values you need to calculate the standard deviation. Figure 1.

P(X)– the probability of the event 3. n– the number of the repetitions of the event However, in finance, many problems related to the expected value involve multiple events. In such a scenario, the EV is the probability-weighted averageof all possible events. To calculate expected value, you want to sum up the products of the X’s (Column A) times their probabilities (Column B). But you will lose more often. Use μ to complete the table.
Examples of Expected Value Formula (With Excel Template) Let’s take an example to understand the calculation of Expected Value in a better manner. Syntax of PROB =PROB(range, prob_range, [lower_limit], [upper_limit]) range – the range of numeric values containing our data ; prob_range – the range of probabilities for each corresponding value in our range Therefore, the general formul… EV– the expected value 2. Expected value formula is used in order to calculate the average long-run value of the random variables available and according to the formula the probability of all the random values is multiplied by the respective probable random value and all the resultants are added together to derive the expected value. Entries in A4:B5 indicate that the appropriate value of z must be between 0.2 and 0.4. According to the laws of probability, mathematical expectation can be simply expressed as the following: E (X) = ∑ i = 1 n x i p i, where x i is the value we get with probability p i. Start in cell C4and type =B4*A4. Now plug these values and probabilities into the expected value formula and end up with: -2 (5/6) + 8 (1/6) = -1/3.
Then drag that cell down to cell C9and do the auto fill; this gives us each of the individual expected values, as shown below. In such a case, the EV can be found using the following formula: Where: 1. Mathematically, the expected value equation is represented as below, Because 0.5 in cell A14 appears in cell B3, it follows that the appropriate z value that yields NORMSDIST = 0.5 is 0 and NORMSINV (0.5) returns 0. Popular Course in this category. Yes, you will win sometimes. To multiply each pair of cells together and add these results, all we need to do is use the sumproduct() function. Add the values in the third column of the table to find the expected value of X: μ = Expected Value = [latex]\displaystyle\frac{{105}}{{50}}[/latex] = 2.1. Related …
In cell B15, you want that value of z where NORMSDIST (z) = 0.6.
