A sequential experiment involves repeatedly drawing a ball from one of two urns, noting the number on the ball, and replacing the ball in its urn. Urn 0 contains a ball with the number 1 and a ball with the number 0, and urn 1 contains 2 balls with the number 1 and one ball with the number 0.The urn from which the first draw is made is selected at random by flipping a fair coin. Urn 0 is used...

We have two urns: Urn A contains 6 red balls and 4 white balls, Urn B contains 4 red balls and 8 white balls. A die is rolled, if a number less than 3 appears; we go to box A; if the result is 3 or more, we go to ballot box B. Then we extract a ball. It is requested: to. Probability that the ball is red and ballot box B. b. Probability that the ball is white.
