Is an irrational number chosen at random is never a rational number?
An irrational number cannot be rational, so choosing at random is an irrelevance.
What is the probability of choosing the 8 winning lottery numbers when the numbers are chosen at random from 0 - 9?
1/3628800
What is the probability of choosing a marble that is blue?
The answer depends on how many blue and non-blue marbles there are, whether the choice is random and how many marbles are chosen. There is no information provided on any of these.
A sample selected in such a way that each members of the population has an equal probability of being chosen?
That is known as a simple random sample, or SRS.
What is the best statistical method for choosing an element who has Multiple properties?
The method will depend on what the population comprises. For example, if every element in the population has multiple properties then simply random selection will suffice.

What kind of sample is taken from the entire population without a person choosing each person?
Random Apex:)
A random sample is a sample in which?
each object/event/person/whatever is chosen randomly from the population.
What is the definition of simple random sample?
There are two equivalent ways of defining a simple random sample from a larger population. One definition is that every member of the population has the same probability of being included in the sample. The second is that, if you generate all possible samples of the given size from the population, then each such sample has the same probability of being selected for use.
What is the purpose of random sampling in a poll?
Random sampling ensures that a bias in the sampled subjects is avoided. It allows for a diverse and fairly chosen sample of the intended population.

The answer depends on how many blue and non-blue marbles there are, whether the choice is random and how many marbles are chosen. There is no information provided on any of these.
What is a survey of a representative sample of the population called?
Random selection.
What is the formula for simple random sampling?
The formula for simple random sampling is: n = N * (X / M) Where: n = number of samples N = population size X = sample size chosen M = total number of units in the population
