WebThere are many methods to generate Gaussian-distributed numbers from a regular RNG. The Box-Muller transform is commonly used. It correctly produces values with a normal distribution. The math is easy. You generate two (uniform) random numbers, and by applying an formula to them, you get two normally distributed random numbers. WebNormally distributed random numbers on an interval have probabilities that follow the normal distribution bell curve, so numbers closer to the mean are more likely to be selected or to happen. $\endgroup$ – Eleven-Eleven.
