Random numbers are often used to select simple random samples from a population frame. The random numbers required for this purpose can be generated by a computer program or from a table of random digits. We will first discuss the use of table of random digits. Discrete uniform probability distribution function, which has possible outcomes between 0 and 9 with equal probability, is used to generate digits in the table. Thus, for each column and row that contains digits in the table, every digit from 0 to 9 has equal probability of appearing in that column and row position. The digits in the table generally generated by a computer and tested to ensure close adherence to the required properties of equal  probability and independency among the digits.
