standard deviation of rolling 2 dice

Two Note that if all five numbers are the same - whatever the value - this gives a standard deviation of zero, because every one of the five deviations is zero.

A Gaussian distribution is completely defined by its mean and variance (or standard deviation), so as the pool gets bigger, these become increasingly good descriptions of the curve. Two Note that if all five numbers are the same - whatever the value - this gives a standard deviation of zero, because every one of the five deviations is zero.
