# Puzzle: Coloured Cards

Three cards are placed in a hat. They are

• A card that is coloured red on both sides.
• A card that is coloured green on both sides.
• A card that is coloured green on one side and red on the other side.
One card is drawn at random from the hat and placed with the green side up on the table (when one side of a card is face up, you can't see what's on the other side). What is the probability that the other side of the card is also green?
