An urn contains five blue balls and six yellow balls. If six balls are selected randomly without being replaced, what is the probability that of the balls selected, two of them will be blue and four of them will be yellow? The probability that of the balls selected, two of them will be blue and four of them will be yellow is (Round to four decimal places as needed.)
7. An urn contains nine blue balls and six yellow balls. If five balls are selected randomly without being replaced probability that of the balls selected, one of them will be blue and four of them will be yellow? (2 points) N-15 n=5 8. The mean number of errors per page made by a member of the word processing pool for a large company is thought 2.6 with the number of errors distributed according to a Poisson distribution. If a...

An urn contains 5 blue balls, 3 yellow balls and 2 red balls. Three balls are drawn without replacement. (i) What is the probability that all three balls are blue? (ii) What is the probability that two balls are blue and one ball is yellow? (iii) What is the probability that at least one of the balls is blue?
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?
In an urn, there are 10 blue balls and 10 red balls. Balls are randomly selected from the urn over and over again. Find the probability that the third blue ball is chosen on the fifth selection under the different assumptions: a) Balls are NOT returned to the urn after selection. b) Balls are returned to the urn after being selected.

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?
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 3 red balls, 2 blue balls, and 5 white balls. A ball is selected and its color noted. Then it is replaced. A second ball is selected and its color noted. Find the probability of: Selecting 2 blue balls (round to 4 decimal places)
