## How do you calculate expected value of winnings?

How to compute a mathematical expected value? The calculation of the mathematical expected value is **to multiply the probability of winning by the bet multiplier (in case of winning)**. Expected value is generally calculated for a bet of 1 unit. Multiply the probability to win by the bet value to know the expected gain.

## How do you calculate game expectation?

In general, to find the expected value for a game or other scenario, **find the sum of all possible outcomes, each multiplied by the probability of its occurrence.**

## How do you calculate expected payoff in game theory?

Choose which player whose payoff you want to calculate. **Multiply each probability in each cell by his or her payoff in that cell**. Sum these numbers together. This is the expected payoff in the mixed strategy Nash equilibrium for that player.

## How is Moneyline calculated?

If you want to bet moneylines now, FanDuel will give you a $500 risk-free bet. Underdog: **Multiply your wager by (Moneyline / 100)**, or divide the amount you want to win by (100 / (100 / Moneyline)). Here’s another example where the odds are closer to 50/50. For every $1 bet on Darren Til, you’ll win $1.02.

## How do you calculate expected mean?

To find the expected value, E(X), or mean μ of a discrete random variable X, simply multiply each value of the random variable by its probability and add the products. The formula is given as. **E ( X ) = μ = ∑ x P ( x ) .**

## What is the formula for game theory?

**ν = ad − bc a − b − c + d** . The expected payoff for the column player is given by the negative of the expected payoff for the row player since it is a zero sum game. The game is called a fair game if the value of the game is ν = 0.
