An urn contains six white balls and four black balls. Two balls are randomly selected from the urn. Let X represent the number of black balls selected.

(a) Identify the probability distribution of X. State the values of the parameters corresponding to this distribution.

(b) Compute P(X = 0), P(X = 1), and P(X = 2).

(c) Consider a game of chance where you randomly select two balls from the urn. You then win $2 for every black ball selected and lose $1 for every white ball selected. Let Y represent the total amount won. Represent the probability distribution of Y as a probability table.

(d) Find the mean and standard deviation of Y. Would you play this game? Explain.

Urn A contains four white balls and three black balls. Urn B contains six white balls...

Urn A contains four white balls and three black balls. Urn B contains six white balls and seven black balls. A ball is drawn from Urn A and then transferred to Urn B. A ball is then drawn from Urn B. What is the probability that the transferred ball was white given that the second ball drawn was white? (Round your answer to three decimal places.) I can't seem to figure this out! Please help! Thank you!

An urn contains two white and two black balls. A ball is drawn at random. If it is white, it is not replaced into the urn, otherwise it is replaced with another ball of the same color. The process is repeated. Find the probability that the third ball drawn is black.

Q2. Two balls are chosen randomly from an urn containing 8 white, 4 black, and 2 orange balls. Suppose that we win $2 for each black ball selected and we lose $1 for each white ball selected. Let X denote our winnings. What are the possible values of X, and what are the probabilities associated with each value i.e. create a discrete probability distribution table for winning amount. Compute the expected value of winnings and standard deviation of winnings. You...

An urn contains n white balls and m black balls. ( m and n are both positive numbers.) (a) If two balls are drawn without replacement , what is the probability that both balls are the same color? (b) If two balls are drawn with replacement (i.e., One ball is drawn and it’s color recorded and then put back. Then the second ball is drawn.) What is the probability that both balls are the same color. (c) Show that the...

An urn contains five red balls, six white balls, and seven blue balls, and a sample of five balls is drawn at random without replacement. (a) What is the size of the sample space? (b) Compute the probability that the sample contains three red balls, one white ball and one blue ball. (c) Compute the probability that the sample contains at least one ball of each color. (d) Compute the probability that all of the balls in the sample are...

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...

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...

1. Consider the following game: An urn contains 20 white balls and 10 black balls. If you draw a white ball, you get $1, but if you draw a black ball, you loose $2. (a) You draw 6 balls out of the urn. What is the probability that you will win money? (b) How many balls should you draw in order to maximize the probability of winning? Hint: Use a computer.

An urn contains 6 white and 10 black balls. The figure gives by the roll of a dice balance indicates the number of balls that will be drawn without delivery of the ballot box. Let A be the event defined by: A: all the balls drawn from the urn are white. What is the probability that the dice has delivered a 3 knowing that A has realized (Use Bayes' Law)?
