It is usually impossible to work out exactly how large population will behave in any given circumstance. However, it may be possible to assign probabilities of different responses to each member of the population and then, using the rules of probability, calculate how the population - as a whole, or on average - is likely to behave.

What was lengendre contribution to statistics?
Lengendre was the one who introduced the importance of probability to statistics.
What is the probability that in a randomly selected sample of 6 people exactly 4 of them are 65 approximately 0.2?
The answer would depend on the demographics of the population: a probability of 0.2 it too high unless the population is from a retirement area.
What is sampling examine well known methods of probability and nonprobability sampling in statistic?
Non probability sampling and probability sampling are different because probability sampling uses random samples. Non probability sampling aren't random, but can still be representative of the population as a whole if done correctly.
What is the probability that a person from a survey relaxes after work?
The answer will depend on the population which is being studied.
What must you know to develop binomial probability distribution?
is median a chafractoristic of population
What is probability sampling and non probability sampling?
In probability sampling,every item in the population has a known chance of being selected as a member.In non-probability sampling, the probability that any item in the population will be selected for a sample cannot be determined.
What is the probability of picking a number from a population of b numbers?
The probability is 1/b.
What is the definition for probability sample?
A probability sample is one in which each member of the population has the same probability of being included. An alternative and equivalent definition is that it is a sample such that the probability of selecting that particular sample is the same for all samples of that size which could be drawn from the population.
What is the importance of balance population resources and environment?
What is the importance of balance population resources and environment?

A population is the totality of items or things?
Probability sampling
In 6.2 of the population is unemployed and your select 40 random people what is the probability that 10 are unemployed?
The probability is approx 0.0001043
What was pierre-simon laplace's contribution to statistics?
he is the one who introduce the importance of probability in statistics
What is the primary characteristic of a probability sample?
In the context of a sample of size n out of a population of N, any sample of size n has the same probability of being selected. This is equivalent to the statement that any member of the population has the same probability of being included in the sample.
What are the differences between probability sampling and non probability sampling?
In a probability sample, each unit has the same probability of being included in the sample. Equivalently, given a sample size, each sample of that size from the population has the same probability of being selected. This is not true for non-probability sampling.
What year will India's population surpass China's?
In all probability, India's population will surpass China's by 2020.
What is the probability for choosing a red marble?
More information is required. Probability by definition is the proportion of a part, called a sample, to the whole, called a population. Thus in this question, we are given the sample only and without the population, it is impossible to calculate the probability. We need to know the size of the population. As a guide, supposing there are 8 red marbles in a jar containing 40 marbles, then the probability of choosing red is 8/40 or 1: 0.2. There is 20 per cent probability of choosing red.
