There are 5 cards with a picture of a rose and 3 cards with a picture of a daisy. Alia keeps all the cards down on a table with the pictures hidden and mixes them up. She then turns over one card 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 Alia turns over has a rose on it? 4 over 7 5 over 8 5 over 7 4 over 5

So she removed a rose card, so now there's 4 rose cards and 3 daisy cards. Total = 4+3 = 7 cards Rose cards = 3 cards Easy enough now?
