Randomness is the lack of pattern or predictability in events. A random sequence of events, symbols or steps has no order and does not follow an intelligible pattern or combination. Individual random events are by definition unpredictable, but in many cases the frequency of different outcomes over numerous 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 occur twice as often as 4. In this view, randomness is a measure of uncertainty of an outcome, rather than haphazardness, and applies to concepts of chance, probability, and information entropy. According to Ramsey theory ideal randomness is impossible especially for large structures, for instance professor Theodore Motzkin pointed out that "while disorder is more probable in general, complete disorder is impossible". Misunderstanding of this leads to numerous conspiracy theories.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, as, for instance, in computational science. By analogy, quasi-Monte Carlo methods use quasirandom 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. Note that 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, of say research subjects, has the same probability of being chosen then we can say the selection process is random.
Behold is a brand of furniture polish produced by Nakoma Products, LLC. Behold furniture polish and Endust dusting aid were previously produced by Sara Lee. When Drackett was sold to S. C. Johnson & Son in 1992, these two products, Endust and Behold, were sold to Sara Lee. In 2010 the product lines Endust and Behold were sold to Nakoma Products LLC. Located in Coal City, Illinois. The company introduced a new glass cleaner and oven/grill cleaner under the Behold brand name in 2012. S. C. Johnson produces Pledge, a similar product to Behold. William R. Johnson, now president of H.J. Heinz, was assistant brand manager for Behold at Drackett, 1974-1977. The National Institutes of Health household products database lists Behold as containing propane and butane and naphtha. Propane and isobutane blends are used as propellants for household cleaners.Aerosol furniture polishes apply a thin layer of silicone oils, rather than the thicker, more durable layer of solid waxes. Fine furniture craftsmen warn that the silicone oils can penetrate through tiny cracks in the finish and make eventual refinishing very difficult.
