1 Calculate the expected value of variable x (or E(x)) (number of trials * probability of success)(adsbygoogle = window.adsbygoogle || []).push({});

2 Calculate the variance (expected value * probability of a failure)

Take everything to the right of the decimal in the variance off. Then the range of future values is E(x) plus/minus the variance.
