There are initially 5 cards with roses and 1 card with a daisy, making a total of 6 cards. After removing one rose card, there are now 4 rose cards and 1 daisy card remaining, a total of 5 cards.
Therefore, the probability that the card Olga turns over next has a rose on it is 4 out of 5. So, the answer is 4 over 5.
