I'm going to challenge those numbers: Using a posterior probability density function for a binomial distribution, the lower bound in Falcon 9 reliability is .9934 with 95% confidence (assuming 450/450 successful trials). The reliability of F9 could be much lower than five 9s and still reasonably give you 450/450 successful trials. There's only a 0.44% chance that F9 reliability is at least five 9's given the data. |
