In a study of helicopter usage and patient survival, among the 59,599 patients transported by helicopter, 184 of them left the treatment center against medical advice, and the other 59,415 did not leave against medical advice. If 40 of the subjects transported by helicopter are randomly selected without replacement, what is the probability that none of them left the treatment center against medical advice? The probability is O. (Round to three decimal places as needed.)
