A bag contains 8 red marbles 5 blue marbles 8 yellow marbles and 6 green marbles.

There are seven black marbles and nine white marbles.

If one marble is selected determine the probability that it is green answer by stanbon 75887 show source. One of them is removed so now there are 17 marbles. 9 blue marbles 8 green marbles 4 red marbles 8 white marbles and 6 yellow marbles. A jar contains 4 black marbles and 3 red marbles.

What is the probability that one of each color is selected. A box contains 8 red marbles 8 green marbles and 10 black marbles. A sample of 12 marbles is to be picked from the box. There are 35 marbles in a bag.

C how many samples contain exactly 7 red marbles or exactly 6 green marbles. Write the probability as a fraction in simplest form a decimal and a percent. What is the approximate probability of drawing two black marbles and then a white marble without replacement. B find probabilities for p bb p br p rb p ww p at least one red p exactly one red 3.

Three marbles are selected at random and without replacement. P r r 9 20 9 20 81 400 2025. So this is all the possible outcomes. Trivially then the answer is frac 1 3 since there is one white.

There s one blue marble. Give your answer as a decimal number with 3 decimal places. There are 18 marbles in total. 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.

And then there s one blue marble in the bag. Two marbles are drawn without replacement from a jar containing 4 black and 6 white marbles. Take out a marble. So i could pick that green marble or that green marble.

Two marbles are drawn without replacement. There are a number of ways of approaching this problem but the easiest solution is to realize that it doesn t matter what order you took the marbles out in. There s two green marbles in the bag. Suppose that an urn contains 4 green marbles 7 black marbles and 9 white marbles.

A draw the tree diagram for the experiment. An urn contains 4 red 6 white and 5 blue marbles. And sometimes this is referred to as the sample space the set of all the possible outcomes. Call it the second marble.

There are seven black marbles and nine white marbles in a bag. This is our denominator.
