One of two urns is chosen at random with one just as likely to be chosen as the other. Then a ball is withdrawn from the chosen urn. Urn 1 contains 5 white and 2 red balls, and urn 2 has 4 white and 3 red balls.
If a white ball is drawn, what is the probability that it came from urn 1?

(1 point) One of two urns is chosen at random with one just as likely to be chosen as the other. Then a ball is withdrawn from the chosen urn. Urn 1 contains 4 white and 5 red balls, and urn 2 has 3 white and 4 red balls. If a white ball is drawn, what is the probability that it came from urn 1? (Hint: Draw a tree diagram first) (1 point) In a random sample of 1,000 people,...
Urn 1 contains 3 red and 6 blue balls, and urn 2 contains 4 red and 3 blue balls. The urns are equally likely to be chosen. a) If a blue ball is drawn, what is the probability that it came from urn 1? b) If a red ball is drawn, what is the probability that it came from urn 2?
Five white balls and two red balls are distributed between two urns A and B in such a way that urn A contains 2 white balls and 2 red balls and urn B contains 3 white balls. At each step, we draw one ball from each urn and place the ball drawn from urn A into urn B and conversely with the ball from urn B. Find the long run proportion of time that urn A will contain 4 white...
Consider 3 urns. The urn A contains 5 white balls and 10 red balls, the urn B contains 9 white balls and 6 red balls and the urn C contains 4 white balls and 9 red balls. A ball is selected from ballot box 1 and placed in ballot box 2, then one ball is taken from ballot box 2 and placed in ballot box 3. Finally, a ball is taken from ballot box 3. What is the probability that...
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....
If you have two urns, and urn 1 contains 2 black balls and 4 white balls and urn 2 contains 5 black balls and 1 white ball, and you randomly pick an urn and draw a ball, what is the probability you chose urn 2 given that the ball you drew was white? a) 1/5 b) 2/3 c) 1/6 d) 1/9
Need help with well-explained solution 1. Assume that there are two urns. The first urn contains 4 red balls, 3 blue balls, and 3 white balls. The second urn contains 2 red balls, 4 blue balls, and 4 white balls. You randomly select an urn and take two balls from the urn. The probability that you pick the first urn is 40%. What is the probability that (a) the two balls are red? (b) the second ball is blue? (c)...
3. Suppose there are 2 urns such that the first urn contains a
white balls and b black balls and the second urn contains c white
balls and d black balls. Flip a coin whose probability of landing
heads is p and select a ball from the first urn if the outcome is
heads and from the second if the outcome is tails. What is a value
for p for which the probability that the outcome was heads given
that...
Three urns U portions: 1,2 and 3 contain red and and yellow balls in the following pro- Red43 4 Yellow 23 7 If a ball is withdrawn from each urn, what is the probability that they are all of th<e same color?
5. (15 points) Four blue and four maize balls are distributed in two urns in such a way that each contains four balls. We say that the systern is in state i, i = (), 1, 2, 3, 4, if the first urn contains i maize balls. At each step, we draw one ba from each urn and place the ball drawn from the first urn into the second, and conversely with the ball from the second urn. Let Xn...
