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.
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.
If there are 50 marbles 15 are blue 8 are yellow and 27 are red what is the probability of green?
There are 15 blue marbles, 8 yellow marbles and 27 red marbles for a total of 50 marbles. Since there are no green marbles in the lot, It is impossible to pull a green marble from the lot. The is no probability whatsoever! "There just ain't no green ones to pull."
What does ratio mean in a math problem?
it means a number verses another number, like a fraction Here;s an example you have 10 white marbles, 3 blue marbles, and 7 green marbles. what is the ratio of green marbles to the total amount of marbles? hat you do is look at the green marbles, and in this case, there are 7. Now add up all the marbles, which is 20. Your ratio is then 7:20.

bassam has some marbles. one third of them are blue, one half of them are red, and the rest are green. If he has 7 green marbles, how many marbles does he have?
Because 1/3 are blue and 1/2 are red and the rest are green we can calculate that 1/6 of the marbles are green. 1/3 = 2/6 1/2 = 3/6 2/6 + 3/6 = 5/6 which leaves 1/6 green. Since there are 7 green marbles we know there must be 7 x 6 total. The answer is 42 marbles.
What is the probability of pulling a yellow-green marble out of the bag?
It depends on how many yellow-green marbles there are, and on how many total marbles there are. There is insufficient information in the question to answer it. Please restate the question, giving this other information.
A box contains 3 white 5 red 2 green and 4 blue marbles two marbles are drawn without replacement what is the probibality of drawing two red marbles?
I believe it would be 5 red marbles of 14 total marbles (5/14)
