P red blue 2 p blue and blue answer by edwin mccravy 18224 show source.
A jar contains only red white and blue marbles.
The probability of finding a red marble would be the number of red numbers in the jar divided by the total number of marbles in the jar.
You have 12 marbles total.
8 20 which equals 2 5.
A bag of marbles contains 5 red 3 blue 2 green and 2 yellow marbles.
Jar a contains 7 red and 2 blue marbles while jar b contains 5 red and 4 blue marbles.
You then pick.
A jar contains 20 marbles.
The marble is blue or red.
There are two jars a and 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.
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.
1 r b w w b r 2 b w r.
A certain jar contains only b black marbles w white marbles and r red marbles.
If one marble is to be chosen at random from the jar is the probability that the marble chosen is red greater than the probability that the marble chosen will be white.
Now if you take out one red marble then there are 11 now in the jar.
B find probabilities for p bb p br p rb p ww p at least one red p exactly one red 3.
Two marbles are drawn without replacement.
If one marble is drawn at random from the jar find the probability that.
A jar contains 4 black marbles and 3 red marbles.
The probability of selecting a green marble at random from a jar that contains only green white and yellow marbles is the probability of selecting a white marble at random from the same jar is.
You would do the exact same thing with any other color as long as you re just picking one marble.
So the total amount of marbles in the jar would be 20.
A draw the tree diagram for the experiment.
A jar contains 4 white 11 blue and 13 red marbles.
The marble is white or blue.
And there are still 5 white marbles.
So the probability of drawing red is 3 12 or 1 4 reduced.
Find the probability of choosing the given marbles without replacement.
The marble is white or red.
A jar contains 3 white marbles 4 red marbles and 5 blue marbles.

If this jar contains 10 yellow marbles what is the total number of marbles in the jar.
