Assume that when an adult is randomly selected, the probability that they do not require vision correction is 19%. If 7 adults are randomly selected, find the probability that exactly 2 them do not require a vision correction. If 7 adults are randomly selected, the probability that exactly 2 of them do not require a vision correction isN (Round to three decimal places as needed.)
