Depends on the color of the marbles, or more specifically, it depends upon how many of the marbles are blue. If 0 marbles are blue, then the chance is 0. If 1 marble is blue, then the chance is 1/4. If 2 marbles are blue, then the chance is 1/2. If 3 marbles are blue, then the chance is 3/4. If 4 marbles are blue, then the chance is 1. These probabilities assume that you draw only once. The other possibilities are that you draw twice, or three times, or four times. If drawing multiple times, it can be done by putting back each marble after it was drawn, or by keeping it out after it has been drawn.

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.
What is the probabilityof choosing a green marble from a jar containing 5 red 6 green and 4 blue marbles?
The probability of choosing a green marble from this jar would be 6/15. You get this answer by adding up the sum of all the marbles.
A bag has 3 blue marbles 2 red ones and 6 green ones all mixed. What is the probability that if one is selected?
that it is a marble? 1. Unless I have lost my marbles.
If a bag contains three red and three blue marbles and if three marbles are chosen without replacement what is the probability that they will be all red or all blue?
There are 6!/3! = 120 possible combinations of marble colour. Of these, only 2 are "good". This gives a probability of 2/120 = 1/60 = 0.0167, or about one and two-thirds of a percent.
What is the least number of turns needed to be certain that you draw a blue marble from 4 red 6 white and 8 blue?
You have to draw out all the red and white marbles than a blue so 4+6+1=11The answer is 11 turns.
A bag contains 3 blue marbles 7 red marbles and 5 yellow marbles If Joe picks 1 marble from the bag at random what is the probability that it will be blue?
1 in 15 chances that the marble will be blue, because there are 15 marbles all together in a bag, and you are only picking one out of it.
What is the probability of picking a red marble and then a blue marble?
None, if all the marbles that you have are yellow!

In a bag of marbles there were 4 red 3 blue 5 green 3 black and 5 orange what are your chances of taking a blue marble out of the bag?
Ok so first you have 20 marbles in all. Since you have 3 blue marbles the fraction would be 3/20 which you can't reduce. To find in decimal form just punch in 3/20!! -Welcome

Want to find out the value of your marbles? There are plenty of web information about all types of old marbles, especially in the Antique Marble and Price Guide, which also has information about the different companies that made marbles, and how they did it. I also found a website with instructions on making marbles.
