Use the following information for the following questions An urn contains 5 red balls, 4 green balls and 4 yellow balls, for a total of 13 balls. A random selection of balls will be made. 3. If 5 balls are randomly selected without replacement, what is the probability of selecting at least 2 red balls, given that at least 1 yellow ball is selected? Hint: this is a conditional probability. Demonstrate how to obtain the answer. a) 0.59 b) 0.61 c) 0.63 d) 0.65 e) 0.67 The answer is 0.65. Thanks

An urn contains 5 red balls, 4 green balls, and 2 yellow balls. Draw 3 balls with replacement (draw a ball, record the color, and put ball back before drwing again). What is the probability that your draw (a) consists of all red balls? (b) consists of all the same color? (c) consists of all different colors? (d) consists of at least one green ball? (e) consists of exactly two green balls and one red ball?
An urn contains 5 blue balls, 5 white balls, 5 red balls, and 5 green balls. Larry is selecting 4 balls at random one after the other without replacement. What is the probability that at least one of the selected balls is blue?
An urn contains 10 red balls. 7 green balls and 4 yellow balls. At random, 5 balls are drawn (without replacement). What is the probability 3 of them are red?
An urn contains four red balls, six black balls, and five green balls. If two balls are selected at random without replacement from the urn, what is the probability that a red ball and a black ball will be selected? (Round your answer to three decimal places.)
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?
4. An urn contains 5 blue balls, 3 green balls, and 7 white balls. (a) A ball is selected from the urn. What are the odds the ball is green? (2 Two balls are selected without replacement. What are the odds the balls are blue and green? (c) Two balls are selected without replacement. What are the odds at least one is blue or at least one is green? (d) Two balls are selected without replacement. What are the odds...
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 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?
An urn contains 3 yellow balls and 9 red balls. We select 4 balls from the urn with replacement. Find the probability that at least one yellow ball is obtained.
