In a probability sample, each person has an equal chance of being chosen for the study, ensuring that the sample is representative of the population from which it is drawn. Convenience sampling (A) is not considered a probability sample because it relies on the availability and convenience of participants. Non-random sampling (C) is also not considered probability sampling because the process of selection is not randomized. Finally, probability samples can be used to generalize findings to the population from which the sample is drawn (D), which would not be possible with non-probability samples.
