A jar contains red white and blue marbles.

A bag of marbles contains 5 red 3 blue 2 green and 2 yellow marbles. Suppose r denotes a red marble and w a white marble. A jar contains 2 red marbles 6 blue marbles 4 white marbles and 12 black marbles. A jar contains 20 marbles.

A jar contains 3 red marbles 7 green marbles and 10 white marbles. So the probability of drawing red is 3 12 or 1 4 reduced. And there are still 5 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.

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 have 12 marbles total. Find the probability of each event.

So the probability of white is 5 11. This random experiment has four possibilities. A jar contains 3 white marbles 4 red marbles and 5 blue marbles. Jar a contains 7 red and 2 blue marbles while jar b contains 5 red and 4 blue marbles.

Two marbles are drawn without replacement. If a marble is drawn from the jar at random what is the probability that the marble will be white. Now if you take out one red marble then there are 11 now in the jar. P red blue 2 p blue and blue answer by edwin mccravy 18224 show source.

A jar contains 4 black marbles and 3 red marbles. A jar contains 5 blue marbles 8 red marbles 4 white marbles and 3 purple marbles.

What is the ratio of white marbles to all marbles. A draw the tree diagram for the experiment. Suppose you pick a marble at random without looking. 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. 4 red 6 white and 10 blue. Find the probability of choosing the given marbles without replacement. Write your answer as a fraction in simplest form.
