What is randomness?
Randomness: the quality or state of being or seeming random (as in lacking or seeming to lack a definite plan, purpose, or pattern).[1]
While unpredictable outcomes are abundant in nature, the same can’t be said for randomness generated by computers. As computers are deterministic devices, it may not be possible to generate truly random numbers purely through a set of computer algorithms.[2]
