1. Randomness

   In common usage, randomness is the apparent or actual lack of pattern or predictability in events. 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 "trials") is predictable. 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. 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.According to Ramsey theory, pure randomness is impossible, especially for large structures. Mathematician Theodore Motzkin suggested that "while disorder is more probable in general, complete disorder is impossible". Misunderstanding this can lead to numerous conspiracy theories. Cristian S. Calude stated that "given the impossibility of true randomness, the effort is directed towards studying degrees of randomness". It can be proven that there is infinite hierarchy (in terms of quality or strength) of forms of randomness.

1. randomness

   Randomness refers to the lack of pattern, predictability, or order in events. A random sequence of events, symbols, or steps often has no order and does not follow an intelligible pattern or combination. In various fields such as physics, statistics, cryptography, computer science, and others, randomness plays a significant role. It's often used in generating data that mimics various phenomena in order to test theories or models.

1. Randomness

   Randomness means different things in various fields. Commonly, it means lack of pattern or predictability in events. The Oxford English Dictionary defines "random" as "Having no definite aim or purpose; not sent or guided in a particular direction; made, done, occurring, etc., without method or conscious choice; haphazard." This concept of randomness suggests a non-order or non-coherence in a sequence of symbols or steps, such that there is no intelligible pattern or combination. Applied usage in science, mathematics and statistics recognizes a lack of predictability when referring to randomness, but admits regularities in the occurrences of events whose outcomes are not certain. For example, when throwing two dice and counting the total, we can say that a sum of 7 will randomly occur twice as often as 4. This view, where randomness simply refers to situations where the certainty of the outcome is at issue, applies to concepts of chance, probability, and information entropy. In these situations, randomness implies a measure of uncertainty, and notions of haphazardness are irrelevant. 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. A random process is a sequence of random variables describing a process 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.

1. randomness

   1. An inexplicable misfeature; gratuitous inelegance. 2. A hack or crock that depends on a complex combination of coincidences (or, possibly, the combination upon which the crock depends for its accidental failure to malfunction). “This hack can output characters 40--57 by putting the character in the four-bit accumulator field of an XCT and then extracting six bits — the low 2 bits of the XCT opcode are the right thing.” “What randomness!” 3. Of people, synonymous with flakiness. The connotation is that the person so described is behaving weirdly, incompetently, or inappropriately for reasons which are (a) too tiresome to bother inquiring into, (b) are probably as inscrutable as quantum phenomena anyway, and (c) are likely to pass with time. “Maybe he has a real complaint, or maybe it's just randomness. See if he calls back.”Despite the negative connotations of most jargon uses of this term have, it is worth noting that randomness can actually be a valuable resource, very useful for applications in cryptography and elsewhere. Computers are so thoroughly deterministic that they have a hard time generating high-quality randomness, so hackers have sometimes felt the need to built special-purpose contraptions for this purpose alone. One well-known website offers random bits generated by radioactive decay. Another derives random bits from chaotic systems in analog electronics. Originally, the latter site got its random bits by doing photometry on lava lamps. Hackers invariably found this hilarious. If you have to ask why, you'll never get it.)

Examples of randomness in a Sentence

1. Alexis karpouzos:

   When one door opens, another closes. this is the eternity's circle, mistakes belongs to us, but not all, the fate mapped out for us to follow, but does not define our choices, beings of necessity and randomness, we're rattling over the abyss in the vicinity of dying stars

2. New York Governor Andrew Cuomo:

   9/11 was so devastating, so tragic and then in many ways we lose so many more New Yorkers to this silent killer, it was a silent explosion that just ripples through society with the same randomness, the same evil that we saw on 9/11.

3. Joseph Luby:

   There have been quite a number of St. Louis County cases where we see African-American men sentenced to death by all-white juries, and it's just not the kind of thing that can be explained by randomness or chance, there's just been a repeated pattern.

4. Brian Brettschneider:

   You can always have a random kind of warm month, season or even year, but when it happens year after year after year after year after year, then statistically it fails the test of randomness and it then becomes a trend.

5. Kilburn Hall:

   Enemies of the all powerful God, guess what folks? The universe doesn't know or care. If you appreciate the miracle of creation is randomness and that's what makes creation a miracle-congratulations. You've made it into the God club.
