Okay, from irc I know you've said 33% for the kids problem and 25% for the coins one, both of which are wrong...

But they are the same concept. The answer has to be the same. It's just simple probability. There are 2 outcomes, with an equal chance of each event. Both are done twice in a row. What's different?
