## What Is Variance?

Many keno games allow the player to play multiple cards at the same time. The players can easily control the variance of any game by how many numbers in common their cards have. The more the cards share the same numbers, the greater the variance.

Mathematical Calculation

Let:

E(x) = Expected value of random variable X.

Cov(x) = The covariance between any two cards.

The variance of a single card can be expressed as:

Var(x)=E(x^2)-(E(x))2

When two cards share the same number then the outcomes of each game will be correlated. This correlated relationship is measured by their covariance. The general formula for the covariance between two random variables x and y is:

Cov(x,y) = E(xy) – E(x)*E(y)

If the numbers in common are the same between any two cards, then for n cards the total variance is:

Total covariance = n*Var(x) + n*(n-1)*Cov(x,y)
