The concept of distribution has existed since ancient times, as people have always needed to exchange goods and services. However, the formal study of distribution, particularly in economics, began to take shape in the 18th century with the works of economists like Adam Smith. The modern understanding of distribution systems, especially in the context of supply chain management and logistics, evolved significantly during the Industrial Revolution in the 19th century.

Who invented the ring main?
The concept of a ring main, which is a power distribution system commonly used in electrical engineering to supply electricity to multiple locations, does not have a single inventor. It has evolved over time through the contributions of various engineers and experts in the field of electricity distribution.
What is difference between skew binomial and symmetric binomial distribution?
In a symmetric binomial distribution, the probabilities of success and failure are equal, resulting in a symmetric shape of the distribution. In a skewed binomial distribution, the probabilities of success and failure are not equal, leading to an asymmetric shape where the distribution is stretched towards one side.
How do the level of product distribution differ?
Selective distribution occurs when manufacturers distribute products through a limited, select number of wholesalers and retailers. Under exclusive distribution, only a single wholesaler or retailer is allowed to sell the product
What is punctate distribution in regard to sense organs?
in regard to sense organs, what is punctate distribution?
The distribution of phenotypes for a typical polygenic trait can often be expressed as?
a bell-shaped curve known as a normal distribution. This distribution shows the range of phenotypes in a population, with most individuals clustering around the average phenotype and fewer individuals at the extremes of the distribution.
Who invented the water supply and distribution and when?
Ashok Gadgil & it was invented in 1987
Who invented skewed distribution?
Nobody invented skewed distributions! There are more distributions that are skewed than are symmetrical, and they were discovered as various distribution functions were discovered.
Who invented frequency distribution?
Nobody invented frequency distribution. Events happen, as is the nature of events. Some events can have different outcomes and a frequency distribution is simply the proportion of times that these different outcomes happen (empirical freq distrib) or are expected to happen based on scientific laws (theoretical freq distrib).
What infrastructure had to change when cars where invented?
Fuel, Maintenance, distribution, education, roadways, police, and administration among others.
Who was the first to use electricity successfully?
Nikola Tesla invented the poly-phase A/C (alternating current) distribution system currently used worldwide.

It has evolved over time through the contributions of various engineers and experts in the field of electricity distribution.
Is normal distribution also a probability distribution?
Yes. When we refer to the normal distribution, we are referring to a probability distribution. When we specify the equation of a continuous distribution, such as the normal distribution, we refer to the equation as a probability density function.
What does the student's t-distribution refer to in statistics?
The Student's T- Distribution is a type of probability distribution that is theoretical and resembles a normal distribution. The Student T- Distribution differs from the normal distribution by its degrees of freedom.
Which distribution is used to find probabilities about the number of independent events occurring in a fixed time period with a known average rate?
The Poisson distribution. The Poisson distribution. The Poisson distribution. The Poisson distribution.
Distinguish between binomial distribution and normal distribution?
Normal distribution is the continuous probability distribution defined by the probability density function. While the binomial distribution is discrete.
What are the three types of spatial distribution?
The three types of spatial distribution are uniform distribution (evenly spaced), random distribution (no pattern), and clustered distribution (grouped together).
True or False A sampling distribution is a probability distribution for a statistic?
The statement is true that a sampling distribution is a probability distribution for a statistic.
