In a study of helicopter usage and patient survival, among the 46,064 patients transported by helicopter, 167 of them left the treatment center against medical advice, and the other 45,897 did not leave against medical advice. If 50 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? (Hint: Use the Five Percent Condition.) Do not round intermediate calculations; only round your final answer.

P(none left against medical advice) = [P0AMA].

P(no transported patients left the treatment center against medical advice) =
