In Random sampling, the probability of selecting an item from the population is:-: (A) Not Known, (B) Known, (C) Undecided, (D) Zero
Answer is B. Probability sampling - Samples selected through probability sampling are also frequently known as random samples . Randomness, however, does not imply that the sample units are selected haphazardly. On the contrary, in this method of sampling, the probabilities for selecting the different samples from a population are specified, and the probabilities for the units of the population to appear in the samples are known.
