Most lotteries use mechanical lottery machines. These are more interesting to watch, and more transparent, both literally and figuratively: the audience can see exactly how the internal workings of the machine operate, and they can watch the balls come out of the machine; generally, the balls are visible during the entire draw.
Drawing lots or drawing straws is a selection method, or a form of sortition, that is used by a group to choose one member of the group to perform a task after none has volunteered for it. The same practice can be used also to choose one of several volunteers, should an agreement not be reached.
Simple random sampling merely allows one to draw externally valid conclusions about the entire population based on the sample. The concept can be extended when the population is a geographic area. [4] In this case, area sampling frames are relevant. Conceptually, simple random sampling is the simplest of the probability sampling techniques.
Drawing straws within a small group: one of four matches is broken to be shorter than the others, and the four are presented to the group to draw from, the chooser of the short match being selected Sortition is commonly used in selecting juries in Anglo-Saxon [ 54 ] legal systems and in small groups (e.g., picking a school class monitor by ...
A random stimulus is any class of creativity techniques that explores randomization. Most of their names start with the word "random", such as random word, random heuristic, random picture and random sound. In each random creativity technique, the user is presented with a random stimulus and explores associations that could trigger novel ideas.

Random numbers are frequently used in algorithms such as Knuth's 1964-developed algorithm [1] for shuffling lists. (popularly known as the Knuth shuffle or the Fisher–Yates shuffle, based on work they did in 1938). In 1999, a new feature was added to the Pentium III: a hardware-based random number generator.
Another model, which generalizes Gilbert's random graph model, is the random dot-product model. A random dot-product graph associates with each vertex a real vector . The probability of an edge uv between any vertices u and v is some function of the dot product u • v of their respective vectors.
