An urn contains 2 blue marbles and 4 red marbles. One marble is removed, its color noted, and not replaced. A second marble is removed and its color is noted.
(a) What is the probability that both marbles are blue? red?
(b) What is the probability that exactly one marble is blue?
Homework Answers
Here 2 blue and 4 red marbles so we are to find
P( exactly one marble is blue)=
(2/6) *(4/5) +(4/6) *(2/5) =16/30=8/15

An urn contains 2 red and 2 green marbles. We pick a marble, record its color, and replace it. We repeat this procedure a second and a third time. The probability distribution for the number of red marbles is given below. Number of red marbles 0 1 2 3 Probability 1/8 3/8 3/8 1/8 For this distribution, the probability of exactly one red marble is given by: O 7/8. 113. оо

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?

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...

a) A urn contains one red marble, one green marble and one blue marble. An experiment consists of taking one marble from the urn, then returning it and drawing a second marble. What is the probability that exactly one red marble is selected? b) What is the probability that exactly one red marble is selected if the experiment is without replacement (marble is not returned)?
