Please answer the following question: An urn contains 12 red balls, 8 white balls and 6...
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...
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...
1. An urn initially contains 6 red and 8 green balls. Each time a ball is selected, its color is recorded, and it is replaced in the urn along with 2 other balls of the same color. Compute the probability that: (a) The first 2 balls selected are green and the next 2 are red? (b) Of the first 4 balls selected, exactly 2 are green? (c) If the second ball selected is green, what is the probability that the...
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....
There are 4 white balls and 6 red balls in an urn. a. Two balls are selected from the urn without replacement, what is the probability of getting 1 white ball in the first selection and 1 red ball in the second selection? b. If the selection is with replacement, what is the probability of getting 1 white ball in the first selection and 1 red ball in the second selection?
An urn contains 15 white balls and 6 green balls. A sample of seven is selected at random. What is the probability that the sample contains at least one green ball? a) 0.258256 b) 0.741744 c) 0.000052 d) 0.944659 e) 0.999948
An urn contains 5 red, 6 blue, and 8 green balls. A. if a set of 3 balls is randomly selected, what is the probability that each of the balls will be the same color? b. if a set of 3 balls is selected but each time a ball is drawn the color is noted and the ball returned, what is the probability the balls will be the same color?
Urn A contains 7 yellow balls and 3 red balls. Urn B contains 10 yellow balls and 7 red balls. Urn C contains 12 yellow balls and 4 red balls. An urn is picked randomly (assume that each urn is equally likely to be chosen), and then a ball is picked from the selected urn. What is the probability that the chosen ball came from urn B, given that it was a yellow ball?
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
Urn A contains 5 green and 3 red balls, and urn B contains 2 green and 6 red balls. One ball is drawn from urn A and transferred to Urn b. Then one ball is drawn from urn B and transferred to urn A. Let X=the number of green balls in urn A after this process. List the possible values for X and then find the entire probability distribution for X.
