Well, 1, 2, 3, 4, 5 out of the total 8 coins are fair. So there is a 5 8's probability. I'll write it here on the branch, actually. So there's a 5 8's chance that I pick a fair coin. And then there is a 3, 1, 2, 3 out of 8 chance that I pick an unfair coin. So if I were to just tell you what's the probability of picking a fair coin, you'd say, oh, 5 8's. What's the probability of an unfair coin?
