Question 508918: With one method of the procedure called acceptance sampling, a sample of items is randomly selected without replacement , and the entire batch is rejected if there is at least one defect. The Newport Gauge Company has just manufactured a batch of aircraft altimeters and 3% are defective.
Question: If the batch contains 4000 altimeters and 100 of them are selected without replacement and tested, what is the probability that the entire batch will be rejected?

---
P(reject) = P(>=1 defect in 100)
= 1 - P(no defects in 100)
= 1 - (0.97)^100
= 1 - 0.0476
= 0.9524
