A bag contains 2 blue marbles 3 yellow marbles 5 green marbles and 6 red marbles if a marble is selected at random what are the chances that it will be either red ot blue?

1. What I Would Do Is Add 2+3+5+6 Which Is 16
2. So Now You Know There Are 16 Marbles
3.Look At How Many Red And Blue Marbles There Are
4. Red=6
5.Blue=2
6. So 6+2=8
7. Your Answer Is 8/16 Or 1/2
8. So The Answer Is 8/16 Or In Simplest Form 1/2

If you have 50 black marbles and 50 white marbles in a bag at most how many times would you have to draw out a marble to get two the same colour?
The maximum number of marbles you have to draw is three. 1) Draw a marble. It is either white or black. 2) Draw a second marble. If it is the same colour as the first marble, we are done after two draws. 3) Otherwise, the drawn marbles have different colours. Draw a third marble. No matter what you draw next, you must have two marbles of the same colour.
What is the probability of choosing an 8 from a standard deck of cards?
either 4 in 52 chances or 1 in 13 chances.
A bag has 6 marbles in iteach marble is either rad blu or green what is the least number of marbles that you must pull ou of the bag to be sure you have two marble the same color?
Since each of the three colours has an equal chance of being drawn, theoretically if you draw four marbles from the bag, you should have at leas two of the same colour.However, there is a 1/3 (33.33%) chance that the first two marbles you pull out will be the same color. There is just a guarantee that you will have two of at least one color after pulling out four.
What is spreadsheet sorting?
It is the process of arranging a group of selected cells in a row or column numerically or alphabetically, in either ascending or descending order.
What is the secret to accurately guessing how many marbles a jar holds?
Marbles are considered spheres, and there's a mathematical rule to define the random close-packing of spheres in a confined space. Basically:Calculate the volume of a single marble (using the formula Vmarble= 4/3πr3 to determine the volume of the sphere from its radius, which is half its diameter).Then calculate the internal volume of the jar, using the formula Vjar= πr2h for calculating the volume of a cylinder.Divide Vjar by Vmarble; then multiply by .6, as this represents how much of the space inside the jar is (probably) filled with marbles. In other words, N ≈ .6 (Vjar/Vmarble). (Obviously, N then needs to be rounded off to the nearest whole number.)Or if this is too much work, you can try counting the number of marbles at the bottom (or at the top), and then counting the number of rows there appear to be. Either way, good luck.
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.
Erry has a total of 23 marbles The marbles are either blue or green He has three more blue marbles than green marbles How many green marbles does he have?
He has 10 green marbles.

10 Green marbles, 13 Blue marbles.
If you put marbles in the water what happens?
It either floats or sinks...put the marbles in water to test them!
There are 6 red marbles 8 blue marbles and 11 green marbles in a bag. What is the probability that you will randomly draw either a red or a blue marble?
The probability is 0.56
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 green marbles does he have?
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
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 green marbles?
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 smallest number of marbles that could either be divided up into bags of 18 marbles or into bags of 42 marbles with no marbles with no marbles leftover in each case?
it's the LCM of 18 and 42 18 = 2x32 42 = 2x3x7 LCM = 2x32x7 = 126
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.
What game has a clear plastic tower and has plastic sticks with marbles on them and you either try to get or prevent the marbles to fall I forget which?
Kerplunk ! I love that game. and you try to get as many sticks out without getting marbles and if you do try not to get to much because if you have the most at the end of the game you lose.
What is the chance of selecting a red queen from a pack of 52 cards?
There are 2 red queens, assuming a randomly shuffled deck the chances of any one card being selected is 1 in 52, therefore the chance of either of the red queens being selected is 2 in 52. This is normally shown as 1 in 26.
How can you calculate the volume of a sample of marbles?
Either: 1) Find the radius of each marble and thus their volume through V = 4/3 x pi x r^3 and then add the volumes up. or 2) Put all the marbles in a measuring jug and fill it up to the top. Pour the water into a separate container and empty the marbles out of the jug. Pour the water back into the jug. Thus: Volume of water with marbles - volume of water without the marbles = volume of marbles
