Does True Randomness Exist?
Everything is random, depending on how much you know
When a layperson thinks of randomness, they think of the outcome of rolling a fair die or tossing a coin. If you roll a fair die, any of the six probable outcomes have an equal chance of showing up. Non technically, we understand that the outcome of rolling the dice was not a result of any known deterministic factor. It showed out of randomness.
A phenomenon is random if the outcome happens haphazardly, unpredictably, or by chance. Broadly, there are two types of randomness;
Randomness due to lack of knowledge: Also called classical randomness, occurs when an outcome seems random to us, but only because of our present understanding or insufficient understanding of science and nature. That means, if we get to know (by experimentation or by advance in science) all the interaction of the factors that affect the phenomenon, we may consider it as predictable and, therefore, nonrandom.
Take, for example, the rolling of a die. If you roll a die, we can say, so far as we can tell, that the outcome is random. That is predicated on the fact that each of the six probable outcomes has the same chances of showing up, and we cannot predict with accuracy what the outcome of the roll would be. However, the rolling of the die is only random because…
