One white ball is inserted into the box containing ball b. All guesses about the original contents of the box (number of white balls) are equally likely. a) What is the probability that we draw a white ball from the box on the first draw? b) Assume that n=3. If a white ball is drawn for the first time, what is the most likely composition of the box?
