Question

There are 5 cards with a picture of a rose and 1 card with a picture of a daisy. Olga keeps all the cards face down on the 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 Olga turns over has a rose on it? 4/54/64/61/5

Answer 1

Total number of cars after Olga removed one rose card from the table = 5

4 rose cards + 1 Daisy card

To find the probability divide the number of rose cards left by the total number of cards left

4/5
