19.
We have two boxes; there are m white balls and one black ball in
the first box, and k white balls and one black ball in the second
box. We randomly choose a box (each choice has the same
probability) and then draw two balls simultaneously from the chosen
box. Let X denote the number of black balls drawn, and Y denote the
number of the box that was chosen. Find the correlation coefficient
of variables X and Y .

A box contains three white balls, two black balls, and one red
ball. Three balls are drawn at random without replacement. Let Y1
be the number of white balls drawn, and Y2 the number of black
balls drawn. Find the distribution of Z = Y1 × Y2

Following are three boxes containing balls. Box #1 contains 2
black balls and 1 white ball. Box #2 contains 2 black balls and 2
white balls. Box #3 contains 1 black ball and 2 white ball. Draw a
ball from Box 1 and place it in Box 2. Then draw a ball from Box 2
and place it in Box 3. Finally draw a ball from Box 3 . What is the
possibility that the last ball drawn, from Box...

An urn contains two white and two black balls. A ball is drawn
at random. If it is white, it is not replaced into the urn,
otherwise it is replaced with another ball of the same color. The
process is repeated. Find the probability that the third ball drawn
is black.

Suppose that we have two bags each containing black and white
balls. One bag contains two times as many white balls as black
balls. The other bag contains two times as many black balls as
white. Suppose we choose one of these bags at random. For this bag
we select five balls at random, replacing each ball after it has
been selected. The result is that we find all balls are white
balls. What is the probability that we were...

possibility tree
One box contains two black balls (labeled B1 and B2) and one
white ball. A second box contains one black ball and two white
balls (labeled W1 and W2). Suppose the following experiment is
performed: One of the two boxes is chosen at random. Next a ball is
randomly chosen from the box. Then a second ball is chosen at
random from the same box without replacing the first ball.
a. Construct the possibility tree showing all possible...

a box contains two red balls , one white ball and one blue ball.
A sample of two balls was drawn randomly, respectively (without
return), If the variable X express the number of white balls and
the variable Y express the number of blue balls in the sample, find

Suppose a bucket contains one white and one black ball. We pick
out a ball equally likely at random and then put the ball back
along with another of the same color. Then we repeat. What is the
probability that the first time we pick a white ball is after the
ith iteration?

An urn contains n white balls and m black balls. ( m and n are
both positive numbers.)
(a) If two balls are drawn without replacement , what is the
probability that both balls are the same color?
(b) If two balls are drawn with replacement (i.e., One ball is
drawn and it’s color recorded and then put back. Then the second
ball is drawn.) What is the probability that both balls are the
same color.
