Before being allowed to enter a maximum-security area at a military installation, a person must pass three independent identification tests: a voice-pattern test, a fingerprint test, and a handwriting test. If the reliability of the first test is 95%, that of the second test is 98.4%, and that of the third is 98.4%, what is the probability that this security system will allow an improperly identified person to enter the maximum-security area? (Round your answer to seven decimal places.)
