  2. Lottery wheeling - Wikipedia

    en.wikipedia.org/wiki/Lottery_wheeling

    The number of combinations in an Abbreviated Wheel is significantly smaller than the number of combinations in a Full Wheel on the same set of numbers. In the example above, the Abbreviated Wheel for pick-6 lottery with 10 numbers and 4 if 4 guarantee has 20 tickets. A full wheel with 10 numbers requires 210 combinations and has 6 if 6 guarantee.

    Numbers game. The numbers game, also known as the numbers racket, the Italian lottery, Mafia lottery or the daily number, is a form of illegal gambling or illegal lottery played mostly in poor and working-class neighborhoods in the United States, wherein a bettor attempts to pick three digits to match those that will be randomly drawn the ...

  4. Random number generation - Wikipedia

    en.wikipedia.org/wiki/Random_number_generation

    Dice are an example of a mechanical hardware random number generator. When a cubical die is rolled, a random number from 1 to 6 is obtained. Random number generation is a process by which, often by means of a random number generator (RNG), a sequence of numbers or symbols that cannot be reasonably predicted better than by random chance is generated.

    A USB-pluggable hardware true random number generator. In computing, a hardware random number generator (HRNG), true random number generator (TRNG), non-deterministic random bit generator (NRBG), or physical random number generator is a device that generates random numbers from a physical process capable of producing entropy (in other words, the device always has access to a physical entropy ...

  7. Pelton wheel - Wikipedia

    en.wikipedia.org/wiki/Pelton_wheel

    The Pelton wheel or Pelton Turbine is an impulse -type water turbine invented by American inventor Lester Allan Pelton in the 1870s. [1] [2] The Pelton wheel extracts energy from the impulse of moving water, as opposed to water's dead weight like the traditional overshot water wheel. Many earlier variations of impulse turbines existed, but they ...

  8. Wheel factorization - Wikipedia

    en.wikipedia.org/wiki/Wheel_factorization

    Wheel factorization. Wheel factorization with n=2x3x5=30. No primes will occur in the yellow areas. Wheel factorization is a method for generating a sequence of natural numbers by repeated additions, as determined by a number of the first few primes, so that the generated numbers are coprime with these primes, by construction.
