a+b=23 b=a+3 a+b a+(a+3)=23 a+a=23-3 2a=20 a=10 green marbles=10 blue marbles =23-10 =13

Let X = the number of green marbles. X+3 = the number of blue marbles. X + (X+3) = 23 2X + 3 = 23 2X = 20 X = 10 or the number of green marbles.
There is 3 bags with 2 marbles one green and one blue what is the probablitly of choosing one blue marble one green marble and then another blue marble?
It is not explicitly stated in the question, but it is assumed that you draw one marble from each bag. In this case, you have unrelated sequential probability, similar to tossing three coins. The answer is 0.53 or 0.125.
A bag that has 7 greens marbles 3 blue marbles and 12 white marbles what is the probability of selecting a white marble on each of the three tries if the marble is placed back after each pick?
12 white marbles from (7+3+12) = 22 marblesChance of a white marble on first pick = 12/22 = 6/11.Chance of a white marble on second and third picks are the same, as the marble is replaced.So, the chance of a white marble three times is 6/11 * 6/11 * 6/11 = 216/1331 = approximately 16.23%

Let X = the number of green marbles. X+3 = the number of blue marbles. X + (X+3) = 23 2X + 3 = 23 2X = 20 X = 10 or the number of green marbles.

He has 10 green marbles.
A bag contains six blue marbles seven red marbles and four green marbles If four marbles are drawn randomly determine the probability that three are green?
It is 1248/57120 = 13/595 = 0.0218 approx.
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 or marbles contains 8 red marbles and 5 green marbles Three marbles are drawn at random at the same time Find the probability that two are red and one is green?
There are 286 possible sets of three, (any 3 from 13). There are 28 pairs of reds and 5 possible greens so probability is 5 x 28 ie 140 out of 286 which is just under half (0.4895).
A box caontains five blue eight green and three yellow marbles. If a marble is selected at random what is the probability that it is yellow?
Three sixteenths, or 19%.
A bag of marbles has three times as many blue marbles as red marbles and the bag has at least 52 marbles in it At least how many blue marbles are in the bag?
at least 39 blue marbles
A box contains five blue eight green and three yellow marbles If a marble is slected at random what is the probability that it is yellow?
3/16
A box contains five blue eight green and three yellow marbles If a marble is slected at random what is the probability that it is not blue?
11/16
A jar contains three colored marbles 10 red 15 green and 25 blue If you were to choose without looking what is the probability of selecting a green marble?
It is 15/50 = 0.3
