It is defined as Var(x) = E(x^2)- E(x)^2

Also, it should be clear that HUSNGs are <<<<<variance than HU cash. As far as showing this mathematically...In HUSNG your outcome is a binomial random variable so the variance is a direct function of the mean so its easy to write down on paper.....In cash, your variance is not a simple function of the mean(because your outcome is a from a normal sampling dist'n) and should be estimated from actual data using the normal distribution.

But at the end of the day its pretty common sensical...to experience high variance in HUSNGs you need to have a very very low win rate because you will need to have lots of bad runs (like losing 5-6 in a row which is rare for a .7 winner) whereas in cash you win a few big pots and break even or lose a little in most pots. So in cash your results are swingy and spread deeply around the mean.

make sense?
