This calculator will tell you the expected value (i.e., the mean) for an F-distribution random variable, given the denominator degrees of freedom. Please enter the necessary parameter values, and then click 'Calculate'. Degrees of freedom 2: ...
To calculate the expected value on a standard calculator, one will first need to know the probability distribution of the random variable. First, go through the outcomes in the probability distribution one-by-one and use the calculator to multiply each one by the corresponding probability. Make...

Expected Value is the expected outcome of a certain investment, which is calculated based on theweighted averageof all possible values of a random variable defined based on their specific probabilities. Portfolio managers may have several assets in their portfolios in different proportion. No the chal...
,ni=1,…,n) and nn the number of all all possible values assumed by our random variable. We can rewrite the above formula using the summation sign as E(X)=∑i=1nxi⋅P(xi)E(X)=i=1∑nxi⋅P(xi) If you've already visited our weighted average calculator, you may have noticed ...
Expected Value (EV) Calculator X: P(X): This calculator uses the following basic formula: E(X) = μX= x1P(x1) + x2P(x2) + ... + xnP(xn) E(X) = μX= i= Where: E(X) is the expected value of the random variable X , ...
Mean & Expected Value - Probability A simple explanation of the mean and expected value of a discrete random variable. Mean and Expected Value of Discrete Random Variables. Try the free Mathway calculator and problem solver below to practice various math topics. Try the given examples, or ty...
To find the expected value or long term average,μ, simply multiply each value of the random variable by its probability and add the products. Example A men’s soccer team plays soccer zero, one, or two days a week. The probability that they play zero days is 0.2, the probability that...
Investors define the expected return as the probable return for a portfolio based on past returns or as the expected value of the portfolio derived from a probability distribution of probable returns. In the short term, the expected return represents a random variable that takes different values ba...
