Answer 2

Answer:

Random sampling refers to the method in which each of the sampling unit (units in the population) has a non-zero probability of being selected into the sample. Simple random sampling is a special case of random sampling when each of the sampling unit has equal chance of being selected.

Non random sampling is a method of sampling wherein, it is not known that which individual from the population will be selected as a sample.
