The ratio of white marbles to black marbles is 7 to 10 of there are 136 marbles in the bag how many marbles are white?

if the balls are in the ratio of 7:10, then in every 7+10 = 17 of them 7 are white and 10 are black.
With 136 marbles there are 136 ÷ 17 = 8 lots
→ there are 8 lots × 7 white/lot = 56 white.

10 Green marbles, 13 Blue marbles.
If you have 2 white marbles and 6 black marbles how many marbles will you have to take out to get a black marble?
The first could be white, the second could also be white, but for the third there are no white left so the third would have to be black. The first or second could be black, but to guarantee at least one black you need to remove 3 marbles.
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 150 marbles some of the marbles are blue and the rest of the marbles are white in the bag there are 21 blue marbles for every 4 white marbles how many of each color marble blue and white are in the bag show or explain your thinking?

If you have 50 black marbles and 50 white marbles in a bag at most how many times would you have to draw out a marble to get two the same colour?
The maximum number of marbles you have to draw is three. 1) Draw a marble. It is either white or black. 2) Draw a second marble. If it is the same colour as the first marble, we are done after two draws. 3) Otherwise, the drawn marbles have different colours. Draw a third marble. No matter what you draw next, you must have two marbles of the same colour.
What is an example for a ratio?
if there are half as many blue marbles as there are red marbles in a bag then the ratio is 1:2 that you will pull a blue marble. it can also be written as 1 over 2 or 1/2 or .5
There are 4 red 4 black and 4 white marbles in a box how many do you have to take out without looking to be sure you have 2marbles of the same color?
4: Because there will be at least 1 of two kinds of marbles, and 2 of the other. Ex: 1 black, 1 red, and 2 whites.
A sack contains red and blue marbles The ratio of red marbles to blue marbles is 43 If there are 16 red marbles in the sack how many blue marbles are in the sack?
This problem doesn't lead to a whole number solution. Are you sure you copied it correctly? Maybe you meant the ratio is 4 to 3. In that case: red/blue = 4/3 blue/red = 3/4 blue = (3 * red) / 4 = (3 * 16) / 4 = 12 blue marbles
