There Are Seven Black Marbles And Nine White Marbles

A how many samples contain at least 1 red marble.

There are seven black marbles and nine white marbles.

And sometimes this is referred to as the sample space the set of all the possible outcomes. A sample of 12 marbles is to be picked from the box. A box contains 8 red marbles 8 green marbles and 10 black marbles. One of them is removed so now there are 17 marbles.

A bag contains 8 red marbles 5 blue marbles 8 yellow marbles and 6 green marbles. Take out a marble. Two marbles are drawn without replacement from a jar containing 4 black and 6 white marbles. There are seven black marbles and nine white marbles in a bag.

There s two green marbles in the bag. C how many samples contain exactly 7 red marbles or exactly 6 green marbles. Fancy word for just a simple idea that the sample. So this is all the possible outcomes.

B how many samples contain exactly 4 red marbles and exactly 3 black marbles. There are 18 marbles in total. 9 blue marbles 8 green marbles 4 red marbles 8 white marbles and 6 yellow marbles. Call it the second marble.

An urn contains 4 red 6 white and 5 blue marbles. Give your answer as a decimal number with 3 decimal places. 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. Three marbles are selected at random and without replacement.

There are 35 marbles in a bag. B find probabilities for p bb p br p rb p ww p at least one red p exactly one red 3. What is the probability that one of each color is selected. Two marbles are drawn without replacement.

Write the probability as a fraction in simplest form a decimal and a percent. There s one blue marble. So i could pick that green marble or that green marble. And then there s one blue marble in the bag.

Suppose that an urn contains 4 green marbles 7 black marbles and 9 white marbles. If one marble is selected determine the probability that it is green answer by stanbon 75887 show source. Trivially then the answer is frac 1 3 since there is one white. P r r 9 20 9 20 81 400 2025.

A draw the tree diagram for the experiment. A jar contains 4 black marbles and 3 red marbles.
