2.3-6. Place eight chips in a bowl: Three have the num- ber 1 on them, two have the number 2, and three have the number 3. Say each chip has a probability of 1/8 of being drawn at random. Let the random variable X equal the number on the chip that is selected, so that the space of X is S = (1, 2, 3). Make reasonable probability assignments to each of these three outcomes, and compute the mean and the variance o2 of this probability distribution.
