An online retailer carried out a random survey on shipments done by its Order Fulfillment Department. In contacting 3,200 customers, the retailer tried to find out if there are problems with the shipments. The survey response rate was 80%. The two tables in Hint at the end of the question can help you with some calculations. (a)[2] Twenty eight shipments were found with problems, and each of those shipments is considered an error. Find DPU (7 decimal places), EPMO (1 decimal place), and the calculated sigma level of the fulfillment service (2 decimal places).

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
