Suppose 400 balls are distributed into 200 boxes in such a way
that no box contains more than 200 balls and each box has at least
one ball. Then there are some boxes that together contain exactly
200 balls.
Suppose 2 boxes:
- Box #1 contains:
+ 5 Black balls.
+ 6 White balls.
- Box #2 contains:
+ 8 Black balls.
+ 4 White balls.
- Two balls are drawn from Box #2 and placed into Box #1.
- A ball is drawn from Box #1.
1- What is the probability that the ball drawn from Box #1 is
White?
2- Suppose that the ball drawn from Box #1 is White, then what is

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...
There are 2 boxes. The first box contains 2 white and 5 black
balls. The second box contains 4 white and 7 black balls. A random
box is chosen and from it a random ball is drawn. a) What is the
probability that the ball is white? b) If the ball is known to be
white, what is the probability that it came from the 1st box?
We have 3 boxes. Box A contains 1 yellow ball and 2 red balls.
Box B conatins 2 yellow balls and 2 red balls. Box C contains 2
yellow balls and 1 red ball. First, we randomly choose between Box
A and Box B. Then we randomly choose a ball from the selected box
and put the ball into Box C. Lastly, we randomly choose a ball from
Box C.
Let E1 be the event that Box A is chosen...

Box 1 contains 3 red balls, 5 green balls and 2 white balls. Box
2 contains 5 red balls, 3 green balls and 1 white ball. One ball of
unknown color is transferred from Box 1 to Box 2. (a) What is the
probability that a ball drawn at random from Box 2 is green? (b)
What is the probability that a ball drawn from Box 1 is not
white?
Two boxes are labelled I and II. Box I contains 4 black balls
and 6 white balls. Box II contains 2 black balls and 8 white balls.
A player randomly selects one box and then randomly draws 2 balls
without replacement from the selected box.
1) What is the probability of obtaining 2 black balls?
2) Given that 2 black balls are obtained, what is the
probability that Box I is selected?
3) Suppose that 20 players conduct the game...
