    Instead of thinking about reliability think of failure. 99.999% reliability = 0.00001 chance of failure. And 95% reliability = 0.05 chance of failure. Assuming failures are independent (they probably are not) the chance of n servers failing is (0.05) n Find n such that (0.05) n = (0.00001) now do it for (0.14) n = (0.00001)
