Let U1 and U2 be two urns such that U1 contains 3 white and 2 red balls, and U2 contains only 1 white ball. A fair coin is tossed. If head appears then 1 ball is drawn at random from U1 and put into U2. However, if tail appears then 2 balls are drawn at random from U1 and put into U2. now 1 ball is drawn at random from U2.
(i) The probability of the drawn ball from U2 being white is
(a) 1330 (b) 2330 (c) 1930 (d) 1130
(ii) Given that the drawn ball from U2 is white, the probability that head appeared on the coin is
(a) 1723 (b) 1123 (c) 1523 (d) 1223
