Answer:
In the "Choosing Balls rom an Urn” example. Determine the following n-step transition probabilities. (a) After...
Consider an urn initially containing N є N balls. For n E Z+, let Xn be the number of balls in the urn after performing the following procedure n times. If the urn is non-empty, one of the balls is removed at random. A fair coin is flipped, and if the coin lands tails then the ball is returned to the urn. If the coin lands heads, the ball is not returned. If the urn is empty, then the coin...
An experiment consists of choosing an urn with the following probabilities that Urn 1, Urn 2, or Urn 3 will be chosen: 1/2, 1/4, and 1/4, respectively. Urn 1 contains 5 brown marbles and 11 clear marbles. Urn 2 contains 15 brown marbles, 7 clear marbles and 12 red marbles. Urn 3 contains 10 brown marbles, 13 clear marbles and 9 red marbles. A marble is then chosen from the chosen urn. What is the probability that Urn 3 was...
Exercise 12.2 In Example 12.1b, find the optimal strategy and the op- timal value when the urn contains three red and four blue balls S. Example 12.1b An urn initially has n red and m blue balls. At each stage the player may randomly choose a ball from the urn; if the ball is red, then 1 is earned, and if it is blue, then 1 is lost. The chosen ball is discarded. At any time the player can decide...
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...
Example. 2 urns. Red urn contains 3 red balls, 2 white balls. White urn contains 1 red ball, 4 white balls. Pick an urn randomly. Randomly select a ball from that urn. Without replacing the 1st ball, select a ball from the urn whose color matches the first ball. Q. Make a tree diagram, complete with probabilities describing this situation. Q. Find the probability that the first ball is white. Q. Find the probability that the second ball is white....
An urn contains 2 balls that are either red or blue. At each step a ball is randomly drawn and replaced with a new ball, having the same color w.p. 4/5, or different color w.p. 1/5. Find the probability that the 5th ball drawn is red, if you start with 2 red balls in the urn. Please explain step by step how the transition probability matrix is formed.
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 three red balls numbered 1, 2, 3, five white balls numbered 4, 5, 6, 7, 8, and two black balls numbered 9, 10. A ball is drawn from the urn. (Enter your probabilities as fractions.) (a) What is the probability that it is red? (b) What is the probability that it is odd-numbered? (c) What is the probability that it is red and odd-numbered? (d) What is the probability that it is red or odd-numbered? (e) What is the probability that it...
An urn contains 20 red balls and 50 blue balls. Two are chosen at random, one after the other, without replacement. (Round your answers to one decimal place.) (a) Use a tree diagram to help calculate the following probabilities: the probability (as a %) that both balls are red % the probability (as a %) that the first ball is red and the second is not % the probability (as a %) that the first ball is not red and...
6. Suppose Xn is a two-state Markov chain with transition probabilities (Xn, Xn+1), n = 0, 1, 2, Write down the state space of the Markov chain Zo, Zi, . . . and determine the transition probability matrix.
