An urn contains 10 balls, 4 red and 6 blue. A second urn contains 16 red balls and an unknown number of blue balls. A single ball is drawn from each urn. The probability that both balls are the same color is 0.44. Calculate the number of blue balls in the second urn. 13. (5pts) A die is rolled three times. Find: a. The probability that the sum is 3. b. The probability that 6 does not appear. c. The probability that the same number appears three times.

An urn consists of 3 green balls, 4 blue balls, and 6 red balls. In a random sample of 6 balls, find the probability that 3 blue balls and at least 1 red ball are selected. The probability that 3 blue balls and at least 1 red ball are selected is?

An urn contains 2 white balls and 8 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 0.3. 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 was the first one (b) the probability that the urn selected was the second one
