The probability that a site has no problem when the machine says that the pipe at the site has no issue is
0.905
Step-by-step explanation:
Confidence level = 95%
Error level = 5% (1 - 95%)
Since the probability that the machine says the pipe has a problem for a site that in fact has an issue = 95% and the pipe has a problem in 10% of the case, this means that the pipe has a problem in exactly 0.095 (10% * 95%).
Therefore, the probability that a site has no problem when the machine says that the pipe at the site has no issue = 0.905 (1 - 0.095).
