- Bad luck - every random sequence has a chance to happen, so some people have to get the bad results, just like some people get the good results. The chance of missing 3 times in a row at a 95% hit chance is 0.05 * 0.05 * 0.05, which is 0.0125%. 1 in 8000 attempts will get that. 10 times in a row has, of course, a MUCH lower chance. But with millions and millions of attempts, someone is going to hit it. But if it happens too often, it's probably #2:
- Bad design/programming. That 95% shown might not actually be 95%. Or they may have butchered the calculation.
Well, I am the poster child for Murphy's Law, if anything can go wrong, it will happen to me.
And that particular example is Bethesda, so bad design is a given. That said, the same thing happens to me in pretty much everything on computers, including the example of the twins/clones, I only saw one for the longest time, and suddenly, then I only saw the other for a while.
