Explanation
★A characteristic of probability sampling is random selection, so the answer is random selection.
★Probability sampling draws a sample from a population by chance.
★Each member has a known, non-zero chance of being selected.
★This is achieved through random selection.
★Randomization helps the sample represent the population fairly.
★Bias and accidental selection are features of non-probability methods.
★So a characteristic of probability sampling is random selection.
