The recent survey conducted in a certain village suggests that 41.26% of all residents are self-employed. Suppose that this result is true for the current population of all villagers. If 31 residents are chosen at random, what is the probability that those who are self-employed are: fewer than 21? at least 14? greater than or equal to 9 but less than 14?
