Homework Answers
Solution
Total number of balls n(T) = 6
Number of blue balls = n(B)=4
Number of white balls = n(W) = 2
P(selecting white ball ) = n(W)/n(T)
= 2/6 = 1/3
Hence answer is B. 1/3

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...

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?
