Find the probability of choosing the given marbles without replacement.
A jar contains red white and blue marbles.
Two marbles are drawn without replacement from a jar containing 4 black and 6 white marbles.
You roll a fair die if you get a 2 or a 3 you pick a random marble from jar a and put it in jar b.
If you remove marbles one at a time randomly what is the minimum number that must be removed to be certain that you have at least 2 marbles of each colour.
Find the probability of each event.
You then pick.
A jar contains 3 white marbles 4 red marbles and 5 blue marbles.

A jar contains 20 marbles.
Suppose r denotes a red marble and w a white marble.
P red blue 2 p blue and blue answer by edwin mccravy 18224 show source.
Write your answer as a fraction in simplest form.
A jar contains 2 red marbles 6 blue marbles 4 white marbles and 12 black marbles.
So the probability of white is 5 11.
Rr rw wr ww p r 3 4 p w 1 4 since the marbles are drawn with replacements p rr 3 4 3 4 9 16 p rw 3 4 1 4 3 16 p w.
And there are still 5 white marbles.
If a marble is drawn from the jar at random what is the probability that the marble will be white.
What is the ratio of white marbles to all marbles.
Suppose you pick a marble at random without looking.
A draw the tree diagram for the experiment.
A jar contains 5 blue marbles 8 red marbles 4 white marbles and 3 purple marbles.
You have 12 marbles total.
Jar a contains 7 red and 2 blue marbles while jar b contains 5 red and 4 blue marbles.
B find probabilities for p bb p br p rb p ww p at least one red p exactly one red 3.
4 red 6 white and 10 blue.
Now if you take out one red marble then there are 11 now in the jar.
A jar contains 3 red marbles 7 green marbles and 10 white marbles.
The probability to randomly draw a marble is 20c1 the probability to draw a white marble from 10 white marbles is 10c1 thus the probability to draw a white marble out of 20 is.
So the probability of drawing red is 3 12 or 1 4 reduced.
There are two jars a and b.
A bag of marbles contains 5 red 3 blue 2 green and 2 yellow marbles.
A jar contains nine blue marbles eight yellow marbles 11 black marbles and 12 red marbles.
