Of all the registered automobiles in a certain state, 10% violate the state emissions standard. Twelve automobiles are selected at random to undergo an emissions test. Answer the following questions by defining the associated random variables. i) Find the probability that exactly three of them violate the standards. ii) Find the probability that fewer than three of them violate the standards. iii) Find the probability that none of them violate the standards. iv) How many of them do you expect to violate the standard on average?
