What does without replacement mean in probability?

Im not good at explaining things but here's an example. If I have 5 red marbles and 6 blue marbles in a bag and I pick one out. I then choose another marble without returning the first marble to the bag. Hope this helps.


How do you shatter marbles?

Wear protective eye gear !first heat marbles in fire until very hot then scoop marbles out with spoon or tongs so you don't burn yourself then drop hot marble into cold water


If you have 2 white marbles and 6 black marbles how many marbles will you have to take out to get a black marble?

The first could be white, the second could also be white, but for the third there are no white left so the third would have to be black. The first or second could be black, but to guarantee at least one black you need to remove 3 marbles.


What is the game marbles?

Marbles is a game that uses marbles along with a circle. The goal is to knock your opponents marbles out of a created circle by flicking your marbles towards theirs. Whoever has all of their marbles outside the circle first loses. ********************** Actually, there are many, many variations of the game. Some are only played in certain countries or regions of countries and not all involve knocking out another marble. A popular marble game in France has you flicking your marble around a track like it was a race. In part of Tennessee/Kentucky area they play Roley Hole which has teams of 2 shooting their marble back and forth in their playing Field going into 3 different holes. Very complex and lots of strategy with that one. There is an old game called potsie where you shot your marble into a single hole. These versions don't use any target marbles - only a shooter. Then there are many versions that do use a target marble. In the US, the National Marbles Tournament plays ringer and the US Marbles Championship plays a modified version of ringer but both involve knocking target marbles out of a ten foot diameter circle. In England, during the British and World Marbles Championship, 49 target marbles are clumped together on a six foot diameter, 4 inch raised ring lightly covered in sand.


A bag contains 8 marbles 4 are blue 3 are green and one is orange you draw out one marble and then another without replacing the first marble Find the probability of drawing 2 blue marbles?

Probability of drawing a blue marble first is 4 in 8 (or 50%) Probability of drawing a blue marble second is 3 in 7 (or 42.85714%) Probablility of drawing blue then blue is the two above multiplied 0.5 * 0.4285714 Which is 0.212142407 or 21% or One in Five.

In a bag there are 4 red marbles 5 white marbles and 6 blue marbles once a marble is selected it is not replaced what are the odds of pulling a red marble than a white marble?

The odds of pulling a red marble on the first try is 4/15 or about .27 and the probability of drawing a white marble the second time if a the first is a red marble is 5/14 or about .36. the odds of both happening is the product of the probabilities of the other events, or 2/21.


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.


If a bag contains 3 green marbles 5 blue marbles and 2 yellow marbles find the probability that the marble is blue?

Assuming that you're only taking out one marble, then:Your sample space --> 3 + 5 + 2 = 10The probability of getting a blue marble on the first draw is 3/10 or 0.3


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%


What is the probability of drawing a white marble then a red marble if there are 3 red marbles and 2 white marbles?

5 marbles. 3 red marbles, 2 white marbles.The probability of drawing a white marble is P(W) = 2/5 = 0.40If the white marble is not returned to the rest of the marbles (no substitution), theprobability that the second marble drawn is a red one is P(R) = 3/4 = 0.75.The probability that the event of drawing first a white marble and without substitutionthe second draw turns a red marble is P(1stW,2ndR) = (2/5)∙(3/4) = 6/20 = 3/10 = 0.30 = 30.0%.If the process of drawing the marbles is with substitution, the probability of thesecond draw turning a red marble is P(R) = 3/5 = 0.60 = 60.0%The probability that the event of first drawing a white marble and after returning themarble back to the original group of marbles (with substitution) the second draw turns a red marble is P(1stW,2ndR) = (2/5)∙(3/5) = 6/25 = 0.24 = 24.0%.


If a box contains 4 red marbles seven white and 5 blue and two marbles are drawn one at a time with replacement What is the probability that both marbles are white?

Since the box contains 16 marbles, seven of them white, then the probability of drawing one white marble is 7/16. If you replace the marble and draw again, the probability of drawing another white marble is still 7/16. The net probability of drawing two white marbles, while replacing the first, is 49/256.

Why are waves not matter and why they don't carry matter?

The idea is that energy is transferred from one point to another. A simple experiment with glass marbles is very illustrative. Put some marbles - say, 3 - in a straight row. Preferably in some kind of groove, so that they don't escape to the sides. Make a 4th. marble knock into the row of marbles from behind. The new marble stays right behind the last marble, but the first marble in the row gets away! Quite simply, the impulse was transferred from each marble to the next - the marbles themselves remained in place. Well, the ones in the middle at any rate.
