What else can I help you with?
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?
8 i think 8 i think I guess it's 6.. and my point is that you have to try it through the worst sequence ever. starting with the red one (the one that is impossible for you to get another one, and will never reach the three same colored wanted) then start getting one of each of the two other colors each time, alternating, so it will take longer for you to have several of the same color: example: red > black > white > black > white > black (3 black ones) or red > white > black > white > black > white (3 white ones) or (just to prove that alternate sequence isn't needed) white > black > black > red > white > (...) (impossible to get any marble without getting the third of it's color, and by not getting the red one, this would have been impossible to reach, so to be SURE, you have to count this one in the first five, or it would come or not in the 5th position) in this case, a longer sequence would have got the three equal-colored marbles some time ago. remembering, that this sequence is just to explain that 6 would do the job, and these balls would have been caught in a handful of marbles =) ps.:sorry for my poor English.
