List two reasons it if better to sample without replacement

List two reasons it if better to sample without replacement when testing batches of products. When sampling without replacement, should you use the multiplication rule for independent or dependent events? Explain your answer.

Solution

8) two reasons are

a)in without out replacement case there will not be a situation where we can pick the same item more then once while testing the batches.

b) in without replacement we get a clear probability what chances are there for the rest items to be either good or bad.

when sampling without replacement we have to use the multiplication rule for both independent or dependent variables because in without replacement he number of items left after we pick one item the number of item left will also reduce.
