A Jar Contains 39 Red White And Blue Marbles

The probability of both happening would be 1 4 x 12 47.

A jar contains 39 red white and blue marbles.

P red blue 2 p blue and blue answer by edwin mccravy 18224 show source. Find the probability of choosing the given marbles without replacement. A jar contains 3 white 4 blue 5 red and 2 green marbles. A draw the tree diagram for the experiment.

Next we could remove 7 more marbles and there is a possibility no matter how small they could all be blue. Pulling out 2 marbles is the same as to taking out one marble and then taking out another marble form whats remaining in the jar. Now if you take out one red marble then there are 11 now in the jar. Two marbles are drawn without replacement from a jar containing 4 black and 6 white marbles.

You would still end up with a chance of 50. You have 12 marbles total. A are red b neither red or green c not white an ordinary pack of 77. If you reach in the jar and pull out 2 marbles at random find the probability that both are red.

We could potential remove 8 marbles and there is a possibility they could all be red. The number of white marbles is three more than the number of green marbles and the number of blue marbles is one more than twice the number of green marbles b g w 20 w g 3 b 2g 1 substitute for b and w and solve for g 2g 1 g g 3 20 4g 4 20 4g. Two marbles are drawn without replacement. B find probabilities for p bb p br p rb p ww p at least one red p exactly one red 3.

Asked 03 25 15 suppose a jar contains 11 red marbles and 37 blue marbles. See a solution process below. For the second marble the probability of getting a red would be 12 47. A jar contains a total of 20 marbles that are blue green or white.

A jar contains 3 white marbles 4 red marbles and 5 blue marbles. For the first marble the probably of getting a red would be 12 48 which is 1 4. So the probability of white is 5 11. And there are still 5 white marbles.

So to be absolutely certain you would have at least 3. If x equals the number of red marbles drawn which of the following tables shows 3545377. If a marble is drawn at random from the jar what is the probability that the marble. Two marbles are drawn.

So the probability of drawing red is 3 12 or 1 4 reduced. We would need to remove 3 more marble to be absolutely certain there was at least three marbles of each color. A jar contains 4 black marbles and 3 red marbles.
