Jeremy asked:
Balls are drawn from a bag initially containing three white balls and five black balls. At each drawing two balls are drawn at random. If both drawn balls are the same color they are set aside and the game continues by drawing two more balls from those remaining in the bag. If at any stqge the two drawn balls are of different colors, the game ends. What is the expected number of bqlls drawn during a game? –Please give an explanation of how to get the answer.
