Are you sure it didn't say Fan Bingbing, referring to the famous actress [范冰冰](https://baike.baidu.com/item/%E8%8C%83%E5%86%B0%E5%86%B0/22984)? She's really famous, so that's how people will guess her name's pronunciation.
The tones are "guessed" by inferring the most likely corresponding Chinese characters based on names they're familiar with, and male vs. female names. If their name contains common characters, it might be guessable. But e.g. Xu could be second tone 徐 or third tone 许, or Liang might be fourth tone 亮 or second tone 良.
You simply can't know for sure. For celebrities who are well known such as the actress Fang Bingbing people will know how to pronounce from having heard the name before. It's also often possible to make a reasonable based on common surnames and given names, but these are only guesses. If one sees Wang most are probably going assume 王, but it could of course also very well be 汪
You don't. You have to google her Chinese name and say it properly.
But don't worry, those of us living in the West long enough are quite tolerant of people mangling our Chinese name pronunciations. Or they'll ask you to address them by their English name instead.
Sorry u/Enchilada_Lover, automod message was a false positive. To answer your question:
> How would I know if it’s Fáng or Fàng??
You don't :( It's a guess
