Suppose that, starting at a certain time, batteries coming off an assembly line are examined one by one to see whether they are defective (let D = defective and N = not defective). The chance experiment terminates as soon as a nondefective battery is obtained.

a. Give five possible outcomes for this chance experiment.

b. What can be said about the number of outcomes in the sample space?

c. What outcomes are in the event E, that the number of batteries examined is an even number?
