In probability sampling, each member of the population has a known, non-zero chance of being selected for the sample, allowing researchers to calculate the probability of any individual's inclusion. This method does not guarantee zero sampling error, small estimation error, or inherently valid results, but it does ensure that the selection process is random and representative.
