Randomness

Computer random number generators are technically pseudorandom, based on deterministic algorithms. For most purposes they're sufficiently random, but cryptography requires special generators.

Probability

In a uniform generator, each number has equal probability of appearing. With many generations, the distribution approaches uniform (law of large numbers).

Applications

Random numbers are used in games, simulations, statistical sampling, cryptography, lotteries, and unbiased decision-making.
