Best ResponseYou've already chosen the best response.0The number of chips of different colors in Fran's bag is shown below: 9 red chips 4 green chips 15 yellow chips Fran takes out a chip from the bag randomly without looking. He replaces the chip and then takes out another chip from the bag. What is the probability that Fran takes out a green chip in both draws? 4 over 28 multiplied by 4 over 28 equal to 16 over 784 4 over 28 plus 4 over 28 equal to 8 over 56 4 over 28 multiplied by 3 over 27 equal to 12 over 756 4 over 28 plus 3 over 27 equal to 192 over 756

Best ResponseYou've already chosen the best response.0There 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
