Difficult Question
Stumped by this question. Does this question make use of independence or some familiar distribution or even Bayes Theorem? Can you even calculate it without being given any values for probability? Here it is:
A pharmaceutical company is getting ready to deliver 100 vials of a flu vaccine. Before delivering those 100 vials, they randomly select 10 vials into the lab for quality testing. If any one of the vials fail the test, the delivery is cancelled. What is the probability that there are 3 or more faulty vials in an APPROVED batch?
