Distribute 13 indistinguishable balls in 6 distinguishable urns.
What is the number of distributions in which the first three cells
contain together AT LEAST 10 balls?
What would be the answer if the balls were distinguishable?
For an urn containing 4 red balls and 6 green balls, let the
number of balls randomly drawn be the number of heads turning up
when 5 fair coins have been previously flipped. What is the
probability of drawing 3 green balls?
13 Balls are in an urn. 4 are blue, 3 are black, 6 are
red.
If two balls are taken out of the urn at the same time, what is
the probability that the balls are of different color? What is the
probability that the balls would be different colors if you took
one ball and put it back before drawing the second?
In a box are six balls with the numbers 2, 6, 7, 13, 23, 34.
(a) (2 points) You draw four balls at the same time. What is the
probability that two of them are prime numbers?
(b) (2 points) Draw a ball, put it back in the box, and draw
another ball. Let A be the event that the first ball is even, and
let B be the event that the product of the two numbers on the two...

There are 6 numbered balls in a bag. Each ball has a distinct
number and the numbers are in {1, 2, 3, 4, 5, 6}. Take 3 balls from
the bag (without replacement) randomly and read the number on each
ball. Let X1 be the maximum number and X2 be the minimum number
among the three observed numbers. (a) Find the marginal p.m.f. of
X1. (b) Find the marginal p.m.f. of X2. (c) Find the joint p.d.f.
of X1 and...
