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 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%.
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.
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 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 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 blue marble?
25/50 gives the probability of selecting a blue marble
8 identical balls are placed at random in three bags. what is the probability that the first bag will contain 3 balls?
The probability that it contains exactly 3 balls is 6/45 = 0.133... recurring.
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
