Random numbers are essential in many fields and applications:
Random numbers follow specific probability distributions. The most common is the uniform distribution, where all outcomes have equal probability. Other important distributions include:
| Distribution | Description | Common Applications |
|---|---|---|
| Uniform | Equal probability for all outcomes | Dice rolls, lottery numbers |
| Normal (Gaussian) | Bell-shaped curve centered around a mean | Natural phenomena, measurement errors |
| Binomial | Number of successes in a fixed number of trials | Coin flips, yes/no surveys |
| Poisson | Rate of rare events in a fixed interval | Website traffic, customer arrivals |
Several statistical tests can verify if a sequence of numbers is truly random:
