A certain jar contains only b black marbles w white marbles and r red marbles.

A jar contains only red white and blue 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. 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 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. P red blue 2 p blue and blue answer by edwin mccravy 18224 show source.

So the total amount of marbles in the jar would be 20. 8 20 which equals 2 5. You have 12 marbles total. The marble is blue or red.

Find the probability of choosing the given marbles without replacement. Jar a contains 7 red and 2 blue marbles while jar b contains 5 red and 4 blue marbles. So the probability of white is 5 11. A jar contains 4 black marbles and 3 red marbles.

Now if you take out one red marble then there are 11 now in the jar. 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. The marble is white or red. 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 from a jar containing 4 black and 6 white marbles. There are two jars a and b. So the probability of drawing red is 3 12 or 1 4 reduced. 4 red 6 white and 10 blue.

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. A jar contains 20 marbles.
