No, you misunderstand me. I'm talking about the probability of getting heads overall. Meaning you don't care which throw it comes from, you just want heads. In which case, if you throw it once, yes, there is a 50% percent chance of not getting heads. But if you throw it twice, there is only a 25% chance of not getting heads at all. Obviously there is still the 50% chance for each throw, but when you combine both throws, there is only one case out of four where you get no heads whatsoever.

Does this make more sense?
