Introduction :
Sampling with replacement :
It is a method in which unit / item may be sampled or selected in the sample again. There is prob. of selecting a item more than once
For example : A box contains 1 red balls, 2 white balls and 4 blue balls. Suppose, 2 balls are selected randomly. Let, first 1 red ball is selected then put that ball again in box and then again second ball is selected, so there is possibility of selecting a red ball again
Sampling without replacement :
