Let U1 and U2...

Question

Let $U_{1}$ and $U_{2}$ be two urns such that $U_{1}$ contains 3 white and 2 red balls, and $U_{2}$ contains only 1 white ball. A fair coin is tossed. If head appears then 1 ball is drawn at random from $U_{1}$ and put into $U_{2}$ . However, if tail appears then 2 balls are drawn at random from $U_{1}$ and put into $U_{2}$ . Now 1 ball is drawn at random from $U_{2}$ .
