The characteristic of equal probability of being selected is the defining feature of random sampling. Cluster sampling involves dividing the population into clusters and randomly selecting some of those clusters to sample. Systematic sampling involves selecting every nth individual from a list of the population. Stratified sampling involves dividing the population into homogeneous strata and then selecting individuals from each stratum proportionally to the size of the stratum. None of these techniques ensure equal probability of selection for all individuals in the population.
