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 bag contains 3 red 4 green and 3 yellow marbles Three marbles are randomly drawn from the bag What is the probability that they are of the same colour and different colours one of each color?
The probability for most of the same colours is most likely green. One of each can be one of each, but there is a small chance you will get more red and yellow than green.
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%.
Jerry has a total of 23 marbles the marbles are either blue or green he has three more blue marbles than green marbles how many marbles does he have?
He will have 13 blue marbles and 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.

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
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 5 green marbles 3 yellow and 2 red marbles. What is the probability of picking three green marbles from the bag without replacement?
To find the answer to probability, first add all the things together (5+3+2=10), then, find the number of things you will be taking from the group of things (3), and put together as a fraction (3/10). So the final answer is 3/10, which is unlikely. :D
