There are seven black marbles and nine white marbles.

C how many samples contain exactly 7 red marbles or exactly 6 green marbles. All of the original white marbles are still in the bag so there is a 4 out of 17 or 4 17 chance that the next marble taken out of the bag will be white. B how many samples contain exactly 4 red marbles and exactly 3 black marbles. And then there s one blue marble in the bag.

What is the probability that one of each color is selected. And sometimes this is referred to as the sample space the set of all the possible outcomes. A bag contains 8 red marbles 5 blue marbles 8 yellow marbles and 6 green marbles. One of them is removed so now there are 17 marbles.

Three marbles are selected at random and without replacement. Suppose that an urn contains 4 green marbles 7 black marbles and 9 white marbles. A how many samples contain at least 1 red marble. There are 18 marbles in total.

P r r 9 20 9 20 81 400 2025. So i could pick that green marble or that green marble. What is the approximate probability of drawing two black marbles and then a white marble without replacement. There s one blue marble.

An urn contains 4 red 6 white and 5 blue marbles. A jar contains 4 black marbles and 3 red marbles. Write the probability as a fraction in simplest form a decimal and a percent. Two marbles are drawn without replacement.

Call it the second marble. This is our denominator. There s two green marbles in the bag. A draw the tree diagram for the experiment.

If one marble is selected determine the probability that it is green answer by stanbon 75887 show source. Take out a marble. Give your answer as a decimal number with 3 decimal places. There are seven black marbles and nine white marbles in a bag.

9 blue marbles 8 green marbles 4 red marbles 8 white marbles and 6 yellow marbles. B find probabilities for p bb p br p rb p ww p at least one red p exactly one red 3. There are 35 marbles in a bag. A sample of 12 marbles is to be picked from the box.

Trivially then the answer is frac 1 3 since there is one white. So this is all the possible outcomes.
