Urn A contains 5 green and 4 red balls, and Urn B contains 3 green and 6 red balls. One ball is drawn from Urn A and transferred to Urn B. Then one ball is drawn from Urn B and transferred to Urn A. Let X = the number of green balls in Urn A after this process. List the possible values for X and then find the entire probability distribution for X.

Urn A contains 5 green and 4 red balls, and Urn B contains 3
green and 6 red balls. One ball is drawn from Urn A and transferred
to Urn B. Then one ball is drawn from Urn B and transferred to Urn
A. Let X = the number of green balls in Urn A after this process.
List the possible values for X and then find the entire probability
distribution for X.

sampled randomly.
Let W denote the number of green balls in the sample when the
draws are done with replacement. Give the possible values and the
PMF of W.

An urn contains 6 red balls and 4 green balls. A sample of 7
balls is selected at random.
a. How many different samples are possible?
b. How many samples contain 5 red and 2 green balls?
c. How many sample contain all red balls?

An urn contains 5 green balls and 8 red balls. One of the
balls is drawn at random.
The drawn ball is returned to the urn with 3 additional balls
of the same color. A second
ball is drawn from the newly constituted urn.
a. What is the probability the second ball is green?
b. Given that the second ball was red, what is the probability
that the first ball was green?

In an urn, there are 5 red balls, 5 green balls, 4 yellow balls,
and 6 white balls. You are drawing balls without replacement.
a. When you draw the first ball, what is the probability that
the ball will be white?
b. Let us assume that you have drawn two balls and both of them
are green. What is the probability that the next ball drawn will be
green?
c. Let us assume that the third ball drawn is also...

Urn 1 contains 8 green balls and 10 red balls. Urn 2 contains 7
green balls and 5 red balls. A die is rolled, if a 1 or 2 is
rolled, a ball is chosen from urn 1, if a 3, 4, 5, or 6 is rolled,
a balls is chosen from urn 2. What is the probability of selecting
a green ball? Please show all work.

An urn contains 10 red balls and 5 green balls. Balls are
randomly selected, one at a time, with replacement, until a red one
is obtained. What is the probability that exactly k draws are
needed? What is the probability that at least k draws are needed?
Define a random variable associated with this experiment. Determine
its probability mass function and cumulative distribution function,
sketch their graphs. Find the expectation, variance and standard
deviation of X.

As shown in Figure 02, an urn contains 12 red balls and 4 green
balls. The red balls are numbered from 1 to 12, and the green balls
are numbered from 1 to 4. One ball is randomly drawn from the urn.
Which of the following answers is correct? (Let: R = red; G =
green; and E = even.)
P(G ∪ R) = 0.000.
P(R|E) = 0.375.
P(G ∪ E) = 0.625.
P(G|R) = 0.500.
