Question 574577: A company purchases shipments of machine components and uses this acceptance sampling plan: Randomly select and test 21 components and accept the whole batch if there are fewer than 3 defectives. If a particular shipment of thousands of components actually has a 6% rate of defects, what is the probability that this whole shipment will be accepted

You can put this solution on YOUR website!

------
Binomial problem with n = 21 and p(defect) = 0.06
---
P(0<= x <=2) = binomcdf(21,0.06,2) = 0.8716
