Bag 1 contains 3 red balls and 7 green balls. Bag 2 contains 8 red balls...
Bag 1 contains 3 red balls and 7 green balls. Bag 2 contains 8
red balls and 4 green balls. Bag 3 contains 5 red balls and 11
green balls. Bag 1 is chosen twice as often as either Bag 2 or Bag
3 (which have the same probability of being chosen). After a bag is
chosen, a ball is chosen at random from that bag. Calculate the
probability that:
a) a red ball is chosen
b) a red ball...

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?

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.

Box A contains 6 red balls and 3 green balls, whereas box B
contains 3 red ball and 15 green balls.
Stage one. One box is selected at random in such a way that box
A is selected with probability 1/5 and box B is selected with
probability 4/5.
Stage two. Finally, suppose that two balls are selected at
random with replacement from the box selected at stage one.

Bowl 1 contains 7 red and 3 white chips. Bowl 2 contains 4 red
and 5 white chips. A chip is randomly selected from Bowl 1 and
placed in Bowl 2, then two chips are drawn from Bowl 2 without
replacement. Find the probability that both chips drawn from Bowl 2
are red.

1) An urn contains 10 balls, 2 red, 5 blue, and 3 green balls.
Take out 3 balls at a random, without replacement. You win $2 for
each green ball you select and lose $3 for each red ball you
select. Let the random variable X denote the amount you win,
determine the probability mass function of X.
