But it does not look like a probability distribution. For it to be a distribution the outputs must be within [0, 1] and sum to 1. ... The core idea of the Normal distribution: ... The normal distribution is the only distribution whose cumulants beyond the first two (i.e., other than the mean and variance) are zero. It is also the continuous distribution with the maximum entropy for a specified mean and variance. Geary has shown, assuming that the mean and variance are finite, that the normal distribution is the only distribution where the mean and variance calculated from a set of independent draws are independent of each other.
