S3: An urn contains 4 black balls and 3 white balls. In our random experiment, on each trial one of the balls is drawn at random and then put back in the urn along with 2 additional balls of the same color. Answer the following questions. (a) color of the first ball drawn is black given that the color of the second ball drawn is white? We conduct two trials, one after the other. What is the probability that the (b) experiment, let's define a discrete random process such that X, is the number of white balls in the urn after the nh trial. Is X, a Markov Chain?
