Urn A contains two red balls and eight blue balls. Urn B contains two red balls and ten green balls. Six balls are drawn from urn A and four are drawn from urn B; in each case, each ball is replaced before the next one is drawn. What is the most likely number of blue balls to be drawn? What is the most likely number of green balls to be drawn?

An urn contains four red balls, two green balls, and three yellow balls. Three balls will be drawn from the urn, one at a time, at random. If the balls are drawn without replacement, what is the probability that the first is red, the second is green, and the third is yellow? If the balls are drawn with replacement, what is the probability the first is red, the second is green, and the third is yellow?

(1 point) There are 5 balls in an urn: 1 red, 1 green, and 3 blue. An experiment has the following rules: i. If a red ball is drawn the experiment ends. ii. If a green ball is drawn, it is set aside and another ball is drawn. iii. If the blue ball is drawn, it is replaced and another ball is drawn. What is the probability that first ball was blue given that the second ball was blue?

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 2 white balls and 8 red balls. A second urn contains 8 white balls and 2 red balls. An urn is selected, and the probability of selecting the first urn is 0.7. 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...

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...
