A bag contains 10 black marbles and 10 white marbles Five marbles are drawn and then replaced each time What is the probability of drawing five white marbles in a row?
It is (1/2)5 = 1/32
What is the equation used to determine probability?
Number of possibilities for one category / Total of all possibilities. For example, if I had a bag of marbles where there are three white marbles and two black marbles. The probability of pulling out a white marble is how many white marbles are in the bag which is: three. But the total of things you can draw out of the bag can either be one of the three white marbles or one of the two black marbles. 3 white marbles+ 2 Black marbles= five marbles. Possibility is 3/5 for drawing a white marble.
A bag contains 10 black marbles and 10 white marbles Five marbles are drawn and then not replaced each time What is the probability of drawing five white marbles in a row?
First white = 10/20 second white = 9/19 third white = 8/18 fourth white = 7/17 firth white = 6/16 Total probability = 10/20 x 9/19 x 8/18 x 7/17 x 6/16 = 21/1292 ~= 0.0163
How do you Write a combination problem and solve it?
A combination problem essentially asks for two answers from different mathematical areas. A simple example could be, "A boy has a bag of marbles. Four marbles are blue. Three marbles are red. Five marbles are white. How many marbles does he have all together? What are the chances of picking a blue marble at random?" The two areas being addressed are simple addition and probability. There are a total of 12 marbles. There is a 1:3 chance of picking a blue marble at random.

Zachary has ninety marbles five-ninths of them are blue how many of the marbles are blue?
Number of marbles in total = 90 Fraction of marbles are blue = five-ninth Number of blue marbles = five-ninth of ninety = 50 So, the answer is 50 blue marbles.

Five twelfths of the marbles in a bag are blue. What fraction of the marbles are not blue?
The answer is 7/12. This is because you just have to subtract 5/12 from 1/1 (12/12).
In a bag of 6 white marble 4 black marbles and 1 red marble what is the least number of marbles that you need to take out of the box to ensure that you get 3 marbles of the same color?
You would need to take out at least 5 marbles to ensure you have 3 of the same color. This is because in the worst-case scenario, you could end up with 2 marbles of each color after drawing 4 marbles (2 white, 2 black) and adding 1 more marble guarantees that you will have at least 3 of one color.
