I read an article criticizing DT Jr's tweet about the 3 skittles in a bowl that will kill you.
The math they use is confusing. They say the chances of an American being killed by a Syrian refugee are 1 in 3.64 billion, but there's no way that's right. If it had happened 0 times, there'd be 0 chance. If it had happened once already, there would be a much larger chance than that number. 1 in 3.64 billion implies it has happened between 0 and 1 times, but that's impossible. It either hasn't happened or has happened a whole number of time(s).
