Listing Outcomes - Combining Probabilities
Design a Game
This simple problem was posed by Daniel Finkel:
Consider this simple game: flip a fair coin twice. You win if you get two heads, and lose otherwise. Its not hard to calculate that the chances of winning are 1/4 . Your challenge is to design a game, using only a fair coin, that you have a 1/3 chance of winning.
Finkel continues, "And here is my recipe for getting the most out of this problem: if you can solve it, do not stop with one answer. Rather, see how many answers you can come up with. Ive posed this problem to many people, and I continue to hear novel solutions."
Here are three familiar solutions (I notice these also turned up quickly in readers' comments to the NYT!):
§ Toss the coin until the first head appears. You win if this takes an even number of tosses
§ Toss the coin twice. You win on HH and lose on HT or TH. If TT appears, ignore the result and make another two tosses.
§ Toss the coin until the first appearance of HTT or HHT on consecutive tosses. You win HTT.
