There's a difference between "this is evidence of discrimination" and "this is proof of discrimination". Getting fired without explanation is definitely evidence of discrimination: most employers are smart enough not to give a reason when firing someone for illegal reasons, so the majority of those firings are going to be "without giving a reason". Conversely, if you do have a legitimate issue, it's (a) usually something you couch the employee on before firing them and (b) means you can give a vague reason like "performance" and thus avoid paying out unemployment. The employee herself can also reasonably observe the social environment - it's not as common these days, but there's still plenty of places that have the Asshole Rockstar who is never going to get fired. It's a bit suspicious when places like that suddenly trot out "culture fit" for the first time, as an excuse to fire a woman. (I'd also say that as long as you don't do anything stupid like TELL people you're discriminating, it's remarkably hard to prove discrimination - legally you're pretty safe there. The other reply does a good job breaking out the math)
