In common usage, randomness is the apparent or actual lack of definite pattern or predictability in information.[1][2] A random sequence of events, symbols or steps often has no order and does not follow an intelligible pattern or combination. Individual random events are, by definition, unpredictable, but if the probability distribution is known, the frequency of different outcomes over repeated events (or âtrialsâ) is predictable.[note 1] For example, when throwing two dice, the outcome of any particular roll is unpredictable, but a sum of 7 will tend to occur twice as often as 4. In this view, randomness is not haphazardness; it is a measure of uncertainty of an outcome. Randomness applies to concepts of chance, probability, and information entropy.
The fields of mathematics, probability, and statistics use formal definitions of randomness. In statistics, a random variable is an assignment of a numerical value to each possible outcome of an event space. This association facilitates the identification and the calculation of probabilities of the events. Random variables can appear in random sequences. A random process is a sequence of random variables whose outcomes do not follow a deterministic pattern, but follow an evolution described by probability distributions. These and other constructs are extremely useful in probability theory and the various applications of randomness.
Randomness is most often used in statistics to signify well-defined statistical properties. Monte Carlo methods, which rely on random input (such as from random number generators or pseudorandom number generators), are important techniques in science, particularly in the field of computational science.[3] By analogy, quasi-Monte Carlo methods use quasi-random number generators.
Random selection, when narrowly associated with a simple random sample, is a method of selecting items (often called units) from a population where the probability of choosing a specific item is the proportion of those items in the population. For example, with a bowl containing just 10 red marbles and 90 blue marbles, a random selection mechanism would choose a red marble with probability 1/10. A random selection mechanism that selected 10 marbles from this bowl would not necessarily result in 1 red and 9 blue. In situations where a population consists of items that are distinguishable, a random selection mechanism requires equal probabilities for any item to be chosen. That is, if the selection process is such that each member of a population, say research subjects, has the same probability of being chosen, then we can say the selection process is random.[2]
According to Ramsey theory, pure randomness is impossible, especially for large structures. Mathematician Theodore Motzkin suggested that âwhile disorder is more probable in general, complete disorder is impossibleâ.[4] Misunderstanding this can lead to numerous conspiracy theories.[5] Cristian S. Calude stated that âgiven the impossibility of true randomness, the effort is directed towards studying degrees of randomnessâ.[6] It can be proven that there is infinite hierarchy (in terms of quality or strength) of forms of randomness.[6]
Ace Grey is my OC
He is also the guy in my pfp
Oh right, this was for forums and not discord usernames
How do we describe Ultimate
A picture of an ultimate art?
DEDAN
Royal guardian of zone one, first boss.
HP: ???/??? CP: ???/???
(props to whoever even recognizes this guy on my pfp)
(complete sentence)
I need to change my user man
mine would be this shit but with an actual emperor status
Should i change my pfp to mario making pizza or should i keep the appa one lol
appa one kinda chill
appa :3
fun fact: i am the reason why badges dont appear next to your username anymore
I will kill you
doesnât change gg
Iâm not even named tom so idk
Hello itâs me, Tsunomaki Watame from Hololiveâs 4th Generation. Pleasure to meet you.
Warm Water
idm
Either just a guy, or two folks stitched together since my user is basically two synonyms wearing a trench coat.
just some guy named nick i guess
this would probably be you since the word dude is deemed to be cool ig
