An urn contains 5 white and 8 red balls. Assume that white balls are numbered. Suppose that 3 balls are chosen with replacement from that urn. Let Yi = 1 if if the ith white ball is selected and Yi = 0 otherwise, i = 1,2:

Find the EXPECTED VALUE of Yi given that a) Y2 = 1; b) Y2 = 0.

(Urn Poker) An urn contains 8 red balls numbered 1 through 8, 8 yellow balls numbered 1 through 8, 8 green balls numbered 1 through 8, and 8 black balls numbered 1 through 8. If 4 balls are randomly selected, find the probability of getting: three of a kind. (Three of a kind is 3 balls of one denomination and a fourth ball of a different denomination. e.g., 5,5,5,2) (c) two pairs. (A pair is two balls of the same...

An urn contains 4 white balls and 6 red balls. A second urn contains 8 white balls and 2 red balls. An urn is selected, and a ball is randomly drawn from the selected urn. The probability of selecting the first urn is 0.7. If the ball is white, find the probability that the second urn was selected. (Round your answer to three decimal places.)

An urn contains 4 white balls and 6 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 0.1. 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...

An urn contains colored balls;5 red balls, 8 green balls, and 10 blue balls. Suppose  If the 3 balls are drawn one after another without replacement, what is the probability that the colors observed will be Red, Green, Blue in this order?  If the three balls are drawn simultaneously from the urn (without replacement), what is the probability that the selected balls will be all different?

Suppose that 3 balls are chosen from an urn which contains 5 red, 6 white and 10 blue balls. Assume X and Y represents, respectively, the number of red balls chosen and summation of chosen red and white balls. (a) Determine the outcomes, and then represent all possible outcomes with a chart of X and Y. (b) Determine pXY [x,y], and then from pXY [x,y] determine, pX[x] and pY [y]. (c) Determine Cov(X, Y ) and ρXY . (d) Determine...

An urn contains 5 green balls and 8 red balls. One of the balls is drawn at random. The drawn ball is returned to the urn with 3 additional balls of the same color. A second ball is drawn from the newly constituted urn. a. What is the probability the second ball is green? b. Given that the second ball was red, what is the probability that the first ball was green?

An urn contains 8 white balls and 5 green balls. A ball is drawn at random, its color is noted, and replaced together with 2 more of the same color. Then the selection is repeated one more time. What is the probability that the ball in the second draw is green? ANSWER: (0.744) Dont know how to get the answer. Would appreciate with the fewest amount of steps in order to get the answer.

Suppose that there is a white urn containing two white balls and three red balls and there is a red urn containing two white balls and four red balls. An experiment consists of selecting at random a ball from the white urn and then (without replacing the first ball) selecting at random a ball from the urn having the color of the first ball. Find the probability that the second ball is red.
