There are 3 cards with a picture of a rose and 1 card with a picture of a daisy. Melody keeps all the cards face down on a table with the pictures hidden and mixes them up. She then turns over one card face up and finds the picture of a rose on it. She removes this card from the table and turns over another card without looking. What is the probability that the card that Melody turns over has a rose on it?
