Detailed explanation-1: -Random sampling ensures that results obtained from your sample should approximate what would have been obtained if the entire population had been measured (Shadish et al., 2002). The simplest random sample allows all the units in the population to have an equal chance of being selected.
Detailed explanation-2: -A simple random sample is meant to be an unbiased representation of a group. It is considered a fair way to select a sample from a larger population since every member of the population has an equal chance of getting selected.
Detailed explanation-3: -Random sampling is a technique in which each sample has an equal probability of being chosen. It attempts to achieve an unbiased representation of the total population.
