And I rounded a little bit. It's actually even slightly higher than that. And this is a pretty powerful tool, or a pretty powerful way to think about it, because it would have taken you forever to write all of the scenarios down. In fact, there would have been 1,024 scenarios to write down. So doing this exercise for 10 flips would have taken up all of our time. But when you think about it in a slightly different way, when you just say, look, the probability of getting at least one heads in 10 flips is the same thing as the probability of not getting all tails. That's 1 minus the probability of getting all tails.
