There are 7 cards with a picture of a rose and 2 cards with a picture of a daisy. Alfa keeps all the cards face down on the 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 Alfa turns over has a rose on it?

    So initially there are 9 cards in total, 7 roses and 2 daisies, giving the probability of drawing a rose 7/9 and a daisy 2/9. Then she draws a rose and removes it. Now there are 8 cards in total. So what would the probability of drawing a rose be now?

    Almost, there aren't 7 roses anymore because 1 was removed. There would now be 6 left.
