2. Find the probability of selecting a marble of each color.
3. Would it be more appropriate to use combinations or permutations
to solve this problem?
4. Find the probability of selecting three red marbles.
5. Find the probability of selecting three green marbles.
6. Find the probability of selecting...

There are 8 red, 3 blue,
2, purple, 3 black,
4 brown marbles in a bag, 5
marbles are selected at random. What is the probability of
selecting at least 2 black marbles?

In a jar, there are 5 neon green marbles, 6 dark purple marbles, 3
bright pink marbles, 4 dark blue marbles, and 12 white marbles.
What is the probability of selecting 2 white marbles assuming the
first marble is replaced?
What is the probability of selecting 2 white marbles where the
first is not replaced?

A jar contains 6 red marbles, 8 green marbles, and 9 blue
marbles?
What is the probability that you choose exactly one of each
color, if you pick 3 from the jar?
I am stumped. It is not 6/23*8/23*9/23. So good luck and thank
you

A glass jar contains 1 red, 3 green, 2 blue, and 4 yellow
marbles. Two people are drawing from one jar one after the other.
Determine the probability of the following events occurring.
A) the first person draws and keeps a yellow marble and then the
second person draws a green marble
B) the first person draws and keeps a blue marble and then the
second person draws a red marble
C) the first person draws and keeps the green...

A jar of marbles has 8 yellow, 3 red, and 9 green marbles. You
select 1 marble, put it back, and then select another. What is the
probability that you choose 2 red marbles? Express the probability
as a fraction in simplest terms. Show your work.
What is the probability that you choose 2 red marbles?

A bag contains 3 red marbles, 5 blue marbles, 8 yellow marbles,
and 7 green marbles. What is the probability of choosing a yellow
