Question 1122752: A pharmaceutical company receives large shipments of aspirin tablets. The acceptance sampling plan is to randomly select and test 30 ​tablets, then accept the whole batch if there is only one or none that​ doesn't meet the required specifications. If a particular shipment of thousands of aspirin tablets actually has a 5​% rate of​ defects, what is the probability that this whole shipment will be​ accepted?

You can put this solution on YOUR website!
Given a 5% rate of defects, probability that there are 0 in this batch is 0.95^30=0.2146
probability there is 1 in this batch is 30*0.95^29*0.05=0.3389
These two together mean there is a 0.5535 probability the shipment will be accepted.
Expected value is 1.5 tablets
