In due course you hand in your money and your guess on a slip of paper. On the following midday, Dimitris, the skipper of the boat, summons the crew to look at the thermometer: It reads 32 ºC - as you predicted. Two more members of the crew predicted the same temperature so you share the money among the three of you.

Later on, as you're lying on the deck, you start thinking what you're going to do with that nice amount of money.

    You could share it with the crew in a party you could give in Xanadú: your destination.
    You could invest it in stocks.
    You think that, without doubt, you must hide that amount of money because it is irresistibly tempting.
