Since each of the three colours has an equal chance of being drawn, theoretically if you draw four marbles from the bag, you should have at leas two of the same colour.However, there is a 1/3 (33.33%) chance that the first two marbles you pull out will be the same color. There is just a guarantee that you will have two of at least one color after pulling out four.
I don't see how this can be done, because when any two odd numbers are added together, the sum is even. If the first two cups each have an odd number the remainder will be 10 - (an even number). Any even number - an even number will equal an even number. Therefore this is not possible.

It is equal to zero in ALL distributions.
A quarter of 40 marbles is equal to 10 marbles. To find a quarter of a number, you divide the number by 4. In this case, 40 divided by 4 equals 10. So, a quarter of 40 marbles is 10 marbles.

In order for 4 red marbles to be one-third of a group and 3 blue marbles to make up one-fourth of the same group the number has to equal 12.

The number of marbles in 3 moles will depend on the molar mass of the marbles. To calculate this, you need to know the molar mass of the type of marble you are referring to (for example, regular glass marbles have a molar mass of about 24 grams/mol). Then you can use Avogadro's number to convert moles to the actual number of marbles.
the probability that a blue one is chosen is 5/10 which is equal to 1/2
