Webb22 jan. 2015 · A simple solution is to use the rule of 3, which is accurate with large N (which you certainly have). Specifically, you can get the upper bound of a one-sided 95% confidence interval (i.e., the lower bound is 0) on the true probability of failure within one year as 3 / N. In your case, you are 95% confident that the rate is less than 0.00003.
