In the first box, there are 4 white and 7 black balls. In the second box, there are 3 white and 6 black balls. A ball is randomly chosen from the first box and transferred to the second box, and then a ball is randomly chosen from the second box and returned to the first box. (a) Find the probability that, after all this, we draw a white ball from the first box. (b) If a black ball is drawn from the first box after the transfers, what is the most likely composition of the first box
