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.

Suppose that an urn contains 8 red balls and 4 white balls. We draw 2 balls from the urn without replacement. Now suppose that the balls have different weights, with each red ball having weight r and each white ball having weight w. Suppose that the probability that a given ball in the urn is the next one selected is its weight divided by the sum of the weights of all balls currently in the urn. Now what is the...

One urn contains 10 red balls and 10 white balls, a second urn contains 8 red balls and 4 white balls, and a third urn contains 5 red balls and 10 white balls. An urn is selected at random, and a ball is chosen from the urn. If the chosen ball is white, what is the probability that it came from the third urn? Justify your answer.

We have three urns: the first urn has 6 red balls and 4 green balls; the second urn has 15 red balls and 5 green balls and the third urn has 20 red balls and 10 green balls. We pick 4 balls from the first urn (sampling with replacement); we select 5 balls from the second urn (sampling with replacement) and we select 10 balls from the third urn (sampling with replacement). Let X1 denote the number of red balls...

An urn contains 3 white balls and 7 red balls. A second urn contains 7 white balls and 3 red balls. An urn is selected, and the probability of selecting the first urn is 0.2. A ball is drawn from the selected urn and replaced. Then another ball is drawn and replaced from the same urn. If both balls are white, what are the following probabilities? (Round your answers to three decimal places.) (a) the probability that the urn selected...

Urn A contains 6 green and 4 red balls, and Urn B contains 3 green and 7 red balls. One ball is drawn from Urn A and transferred to Urn B. Then one ball is drawn from Urn B and transferred to Urn A. Let X = the number of green balls in Urn A after this process. List the possible values for X and then find the entire probability distribution for X.

2. Urn A contains 6 green and 4 red balls, and Urn B contains 3 green and 7 red balls. One ball is drawn from Urn A and transferred to Urn B. Then one ball is drawn from Urn B and transferred to Urn A. Let X = the number of green balls in Urn A after this process. List the possible values for X and then find the entire probability distribution for X.

Given 3 urns, one contains 2 black balls, the second contains 2 white balls, and the third contains 1 ball of each color. An urn is chosen at random and a ball is drawn from it -- the ball is white. What is the probability that the other ball in that urn is also white?

Urn A has 8 Red balls and 5 Green balls while Urn B has 1 Red ball and 3 Green balls. A fair die is tossed. If a “5” or a “6” are rolled, a ball is drawn from Urn A. Otherwise, a ball is drawn from Urn B. (a) Determine the conditional probability that the chosen ball is Red given that Urn A is selected? (b) Determine the conditional probability that the chosen ball is Red and Urn B...

Urn A has 17 white and 4 red balls. Urn B has 9 white and 13 red balls. We flip a fair coin. If the outcome is heads, then a ball from urn A is selected, whereas if the outcome is tails, then a ball from urn B is selected. Suppose that a red ball is selected. What is the probability that the coin landed heads? n
