The ABCD Electronics Company has just manufactured 7000 write-rewrite CDs, and 50 are defective (although they don't know this). Rather than test all the CDs, they use acceptance sampling and randomly select 3 of the CDs for testing. What is the probability that one or more of the CDs sampled will be defective and the entire batch will be rejected? (Hint: Think about the compliment of this event ) Report the answer as a percent rounded to one decimal place accuracy.
