Question 429058: Before being allowed to enter a maximum security area at a military installation, a person must pass 3 identification tests: a voice pattern test, a fingerprint test, and a handwriting test. If the reliability of the first test is 97%m the reliability of the second test is 98.5%, and the third is 98.5%m what is the probability that this security system will allow an improperly identified person to enter the maximum security area?
Thx any help is appreciated

Hi

reliability of the first test is 97%m the 2nd is 98.5%, and the 3rd is 98.5%

 P(improperly identified person entering) = .03*.015*.015
