Let U(1) and U(2) be two urns such that ...

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, than 1 ball is drawn at random for `Us_(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)`
The probability of the drawn ball from `U_(2)` being white is

A

`(13)/(30)`

B

`(23)/(30)`

C

`(19)/(30)`

D

`(11)/(30)`

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. Given that the drawn ball from U2 is white, the probability that head appeared on the coin is
