With one method of a procedure called acceptance sampling, a sample of items is randomly selected without replacement and the entire batch is accepted if every item in the sample is okay. The ABC Electronics Company has just manufactured 2100 write-rewrite CDs, and 130 are defective. If 6 of these CDs are randomly selected for testing, what is the probability that the entire batch will be accepted?
