As we have seen in Chap. 10 , probability deduces what is likely to happen when an experiment is performed. The entire pool of subjects in an investigation is called a population. It may be challenging to involve the whole population in the experiment. Instead, random samples may be chosen so that every member of a population has an equal chance of being selected as any other member. People use statistics obtained from these samples to describe the entire population.

It may be challenging to involve the whole population in the experiment.
