Assume that when an adult is randomly selected, the probability that they do not require vision correction is 16%. If 13 adults are randomly selected, find the probability that fewer than 5 of them do not require a vision correction. If 13 adults are randomly selected, the probability that fewer than 5 of them do not require a vision correction is (Round to three decimal places as needed.)
