Assume that a bag initially contains 6 balls: 2 red, 2 green and 2 blue balls. At each step, you choose a ball from the bag at random, note its color, but do not put it back into the bag. Instead, you add to the bag two balls, which are of of two different colors, and different in color from the color of the removed ball. (For example, if you choose a red ball in the first step, then after...

We have a bag that contains n red balls and n blue balls. At each of 2n rounds we remove one of the balls from the bag randomly, and place it in one of available n bins. At each round, each one of the balls that remain in the bag is equally likely to be picked, as is each of the bins, independent of the results of previous rounds. Let Nk be the number of balls in the k-th bin...

Bag 1 contains 3 red balls and 7 green balls. Bag 2 contains 8 red balls and 4 green balls. Bag 3 contains 5 red balls and 11 green balls. Bag 1 is chosen twice as often as either Bag 2 or Bag 3 (which have the same probability of being chosen). After a bag is chosen, a ball is chosen at random from that bag. Calculate the probability that: a) a red ball is chosen b) a red ball...
