Gambler and Four Coins
A Gambler has four coins in his pocket. Two are double-headed, one is double-tailed and one is normal coin. The coins cannot be distinguished until one looks at them. The gambler takes a coin at random, opens his eyes and sees that the upper face of the coin is the head. What is the probability that the lower face is a head? Given answer is 4/5. I think it should be 2/3.
