Probability samples are those governed by the laws of probability(mcdaniel and gates, 1999) with such samples, each item or individual in the set population has equal chance of being selected to participate in the study it is therefore founded on objectivity non-probability samples, on the other. Sampling is the use of a subset of the population to represent the whole population or to inform about (social) processes that are meaningful beyond the particular cases, individuals or sites studied probability sampling, or random sampling.
