If he wasn't putting the fish back in, then the second sunfish, you would have a nine out of 20 chance of the second one being a sunfish. But in this case, they keep replacing the fish every time they catch it. So there's a 1 8th chance that Jeremy catches three sunfish. So this right over here is 1 8th. And one minus 1 8th, this is 7 8ths. 7 8ths. So you have a 1 8th chance of paying $100, and a 7 8ths chance of getting $20.
