Problem 3: An urn contains 17 balls marked LOSE and 3 balls marked WIN. You and an opponent take turns selecting a single ball at random from the urn without replacement. The person who selects the third WIN ball wins the game. It does not matter who selected the first two WIN balls.
(c) If you draw first, what is the probability that you win? Hint: You could win on your second, third, fourth, . . . , or tenth draw, but not on your first.
(d) Would you prefer to draw first or second? Why?

An urn contains six balls, three marked WIN and three marked LOSE. You and another player take turns selecting a ball from the urn, one at a time. The first person to select the third(last) WIN bal is the winner. If you draw fist. 2. (a) Assuming that the sampling is done without replacement i. Let X be the number of draws needed to determine the winer. Find the p.m.f. of X ii. Find the probability that you will win...
1.4-15. An urn contains 10 red and 10 white balls. The balls are drawn from the urn at random, one at a time. Find the probabilities that the fourth white ball is the fourth, fifth, sixth, or seventh ball drawn if the sampling is done (a) With replacement. (b) Without replacement. (c) In the World Series, the American League (red) and National League (white) teams play until one team wins four games. Do you think that the urn model pre-...
Part A An urn contains 17 balls identical in every respect except color. There are 6 red balls, 8 green balls, and 3 blue balls. You draw two balls from the urn but replace the first ball before drawing the second. Find the probability that the first ball is green and the second ball is blue. Group of answer choices 0.088 0.038 0.083 0.64 Part B An urn contains 17 balls identical in every respect except color. There are 6...
An urn contains 17 balls identical in every respect except color. There are 6 red balls, 8 green balls, and 3 blue balls. You draw two balls from the urn without replacement. Find the probability that the first ball is red and the second ball is green. Group of answer choices A) 0.051 B) 0.166 C) 0.176 D) 0.048
2. An urn contains two green balls and three red balls. Suppose two balls will be drawn at random one after another and without replacement (i.e., the first ball is not returned to the urn before the second one is drawn). (a) Find the probabilities of the events A-I A green ball appears in the irst draw (Note, in event B, the first draw is supposed unknown, for example, after the first draw,you do not look at what color the...
An urn contains 4 white balls and 6 red balls. A second urn contains 6 white balls and 4 red balls. An urn is selected, and the probability of selecting the first urn is 0.8. 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...
An urn contains 3 red balls and 7 yellow balls. Suppose we select two balls from the urn without replacement. A. Referring to no replacement, find the probability that one ball is red and one ball is yellow B. Referring to no replacement, find the probability that the first ball is yellow or the second ball is yellow
2. 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...
An urn contains 10 balls, 3 of which are white. Three players - A, B, and C - successively draw from the urn. Each ball is replaced after it is drawn. The winner is the first one to draw a white ball. (a) Find the probability that A wins. (b) Find the probability that B wins.
An urn contains 7 white balls and 3 black balls. Two balls are selected at random without replacement. What is the probability :1 The first ball is black and the second ball is white.? 2: One ball is white and the other is black? 3:the two balls are white ?
