Random number generation uses the browser's Math.random(), which returns a pseudo-random floating-point number in [0, 1). For cryptographically secure random numbers, use the Web Crypto API (crypto.getRandomValues()). Pseudo-random generators are suitable for simulations, games, and testing, but should not be used for security-sensitive purposes like generating encryption keys or passwords. The distribution statistics help verify that generated numbers are roughly uniformly distributed across the specified range.
