A jar contains only red white and blue 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.

So the probability of white is 5 11. Now if you take out one red marble then there are 11 now in the jar. A jar contains 4 white 11 blue and 13 red 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.

1 r b w w b r 2 b w r. You would do the exact same thing with any other color as long as you re just picking one marble. Jar a contains 7 red and 2 blue marbles while jar b contains 5 red and 4 blue marbles. The marble is white or red.

Two marbles are drawn without replacement from a jar containing 4 black and 6 white 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. 8 20 which equals 2 5. The marble is white or blue.

A bag of marbles contains 5 red 3 blue 2 green and 2 yellow marbles. If this jar contains 10 yellow marbles what is the total number of marbles in the jar. 4 red 6 white and 10 blue. So the total amount of marbles in the jar would be 20.

The marble is blue or red. And there are still 5 white marbles. So the probability of drawing red is 3 12 or 1 4 reduced. A jar contains 4 black marbles and 3 red marbles.

A draw the tree diagram for the experiment. A certain jar contains only b black marbles w white marbles and r red marbles. A jar contains blue green and white marbles. Find the probability of choosing the given marbles without replacement.

Two marbles are drawn without replacement. 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. There are two jars a and b. A jar contains 20 marbles.

You have 12 marbles total.
