I came in doubt because of some gameshow. Can't remember which. The question was something around the lines of, "How many prime numbers between 1 and 10?"

You are given twelve gold coins and a simple balance scale. One of the coins is counterfeit, but it is not known whether it is lighter or heavier than the other coins. You must find it, using only three weighings with the scale.

This is quite hard. You must consider & show all possibilities to get 10 more points ;). Give it a try...!

determined by a coin toss, with the outcome of one coin toss having no effect on the others. Each person can see the other players hats but not his own. No communication of any sort is allowed, except for an initial strategy session before the game begins. Once they have had a chance to look at the other hats, the players must simultaneously guess the color of their own hats or pass. The group will win if at least one player guesses correctly and no players quess incorrectly. One obvious strategy for the players, for instance, would be for one player to always guess "red" while the other players pass. This would give the group a 50% chance of winning the game. Can you device a better strategy?
