Marble is commonly white, but it can also be found in various colors such as gray, beige, pink, and green. The color of marble is determined by the minerals present in the rock and can vary depending on the location where it is quarried.
There has to be 12 marbles in the group. If 4 are red that is 1/3 of 12 and if 3 are blue that is 1/4 of 12. The rest can be any color. That is how you explain how four red marbles can make up 1/3 of a group of marbles and three blue marbles make up 1/4 of the same group :)
The streaks produced in marbles are a product of the impurities present in the sedimentary carbonate rocks such as silt durring metamorphisis.
That depends what you want to measure: its diameter, its mass, its weight, its color, etc.
Most standard marbles measure around 1 inch in diameter, but some larger novelty marbles can reach up to 3 inches. These larger marbles are often used for display or decorative purposes.

The theoretical probability of randomly picking each color marble is the number of color marbles you have for each color, divided by the total number of marbles. For example, the probability of selecting a red marble is 3/20.

Most marbles are not rare. Most marbles are decorative and not really even marbles. It is always good to check the value of the specific marble you have to see if it is real or worth anything.
A simple technique to distinguish between red and blue marbles of the same size and mass is to use a color detection method, such as a camera with image processing software or a color sensor. This allows for the automatic identification of the marbles based on their color. Alternatively, a manual sorting method can involve using a light source to visually separate the marbles by color.
