Question2.
An urn initially contains r red balls and b blue balls. In each step, a ball is chosen uniformly at random, and then put back into the urn together with a new ball of the same color. Let Ri be the event that in step i a red ball is chosen from the urn. Show that P(R1 ∩ R2) = P(R2 ∩ R3).

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.)

9.84. Suppose an urn has b blue balls and r red balls. An experiment consists of picking a ball at random from the urn, note its color and then put it back into the urn and add one more ball of the same color to the urn. Suppose we repeat this experiment twice. What is the probability that we get a blue ball in the second attempt?

ASAP PLEASE olya’s urn model supposes that an urn initially contains r red and b blue balls. At each stage a ball is randomly selected from the urn and is then returned along with m other balls of the same color. Let Xk be the number of red balls drawn in the first k selections. (a) Find E[X1]. (b) Find E[X2]. (c) Find E[X3]. (d) Conjecture the value of E[Xk ], and then verify your conjecture by a conditioning argument....

Urn A contains two red balls and eight blue balls. Urn B contains two red balls and ten green balls. Six balls are drawn from urn A and four are drawn from urn B; in each case, each ball is replaced before the next one is drawn. What is the most likely number of blue balls to be drawn? What is the most likely number of green balls to be drawn?

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.

6. A jar contains 5 red balls and 5 black balls. Two balls are successively drawn from the jar. After the first draw the color of the ball is noted, and then the selected ball is returned to the jar together with another ball of the opposite color. In other words, if a red ball is drawn it is returned to the jar together with another black ball; if black ball is drawn it is returned to the jar together...

An urn contains three red balls, two blue balls and one yellow ball. Our experiment is to draw a ball from an urn, replace it, and draw another. Define a random variable δ: Ω → R by δ(ω) = 1 if you draw the same color twice in a row, and δ(ω) = 0 otherwise. What is the expected value of δ?
