Please show your work. The answer is only for reference.

Suppose that an urn contains 7 green, 8 red, and 9 yellow balls. You pick a ball at random and replace it. You then do this 9 more times (making 10 times altogether). What is the probability that you selected green 2 times, red 3 times, and yellow 5 times? (Hint: multinomial distribution.) Answer: .0589

An urn contains five blue, six green and seven red balls. You choose five balls at random from the urn, without replacement (so you do not put a ball back in the urn after you pick it), what is the probability that you chose at least one ball of each color?(Hint: Consider the events: B, G, and R, denoting respectively that there are no blue, no green and no red balls chosen.)

An urn contains 9 red balls, 7 blue balls and 6 green balls. A ball is selected and its color is noted then it is placed back to the urn. A second ball is selected and its color is noted.

Urn A contains 5 green and 3 red balls, and Urn B contains 2 green and 6 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.

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...

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.

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.
