Kiki has a bag filled with 10 blue and 6 red balls. She draws out balls from the bag two at a time. If they are of the same color, she adds a blue ball to the bag. If they are of different colors, she adds a red ball to the bag. She has a big supply of blue & red balls and does not put the removed balls back in the bag. What will be the color of the last ball left in the bag? |
