A bag contains 5 red marbles 3 blue marbles and 1 green marble. A randomly drawn marble is not blue?
To find the probability of drawing a marble that is not blue, we first calculate the total number of marbles, which is 5 red + 3 blue + 1 green = 9 marbles. The number of marbles that are not blue is 5 red + 1 green = 6 marbles. Therefore, the probability of drawing a marble that is not blue is 6 out of 9, which simplifies to 2/3.
What is the probability of not drawing a green marble?
To calculate the probability of not drawing a green marble, first determine the total number of marbles and the number of green marbles. The probability of not drawing a green marble is then given by the ratio of the number of non-green marbles to the total number of marbles. This can be expressed as: [ P(\text{not green}) = \frac{\text{Number of non-green marbles}}{\text{Total number of marbles}}. ] Without specific numbers, the exact probability cannot be computed.
In a bag of marbles you have three green two yellow six blue and nine red marbles. What is the probability of picking a red marble from the bag?
To find the probability of picking a red marble, first determine the total number of marbles in the bag, which is 3 (green) + 2 (yellow) + 6 (blue) + 9 (red) = 20 marbles. The number of red marbles is 9. Therefore, the probability of picking a red marble is the number of red marbles divided by the total number of marbles, which is 9/20 or 0.45.
Is the probability that a blue marble will NOT be selected from a bag containing 9 red marbles 6 blue marbles 7 green marbles and 11 yellow marbles if one is selected randomly?
To find the probability that a blue marble will NOT be selected, first calculate the total number of marbles: 9 red + 6 blue + 7 green + 11 yellow = 33 marbles. The number of non-blue marbles is 9 red + 7 green + 11 yellow = 27 marbles. Therefore, the probability of NOT selecting a blue marble is 27/33, which simplifies to 9/11.
What is the experimental probability of choosing a green marble if there are 7 red 9 yellow 14 green and 10 purple?
To find the experimental probability of choosing a green marble, first calculate the total number of marbles: 7 red + 9 yellow + 14 green + 10 purple = 40 marbles. The probability of choosing a green marble is the number of green marbles divided by the total number of marbles, which is 14 green / 40 total = 0.35. Thus, the experimental probability of choosing a green marble is 0.35, or 35%.
A bag contains 6 purple marbles and 7 white marbles Two marbles are drawn at random One marble is drawn and not replaced Then a second marble is drawn What is the probability that the first marble?
There are 13 marbles in total. The order is specified.P(1st is white and the 2ndis purple) = (7/13)(6/12) = (7/13)(1/2) = 7/26.
If A bag contains 3 red marbles and 5 purple marbles One marble is drawn at random and not replaced Then a second marble is drawn at random What is the probability that the first marble is purple and?
3/5
A bag contains 5 red marbles 3 blue marbles and 1 green marble. A randomly drawn marble is not blue?
To find the probability of drawing a marble that is not blue, we first calculate the total number of marbles, which is 5 red + 3 blue + 1 green = 9 marbles. The number of marbles that are not blue is 5 red + 1 green = 6 marbles. Therefore, the probability of drawing a marble that is not blue is 6 out of 9, which simplifies to 2/3.
A bag contains five green marbles and four red marbles what is the odds of in favor picking a green marble on the first selection?
There is a one in 2 chance of getting a green marble.
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.
How do you play a game of marbles with jokers included in the rules?
To play a game of marbles with jokers included in the rules, each player starts with a set number of marbles and a joker marble. The joker marble can be used strategically to gain an advantage during the game. Players take turns shooting their marbles towards a target, trying to knock out their opponent's marbles. The joker marble can be used to hit other marbles or to protect your own marbles from being knocked out. The player who knocks out all of their opponent's marbles first wins the game.
What is the probability of not drawing a green marble?
To calculate the probability of not drawing a green marble, first determine the total number of marbles and the number of green marbles. The probability of not drawing a green marble is then given by the ratio of the number of non-green marbles to the total number of marbles. This can be expressed as: [ P(\text{not green}) = \frac{\text{Number of non-green marbles}}{\text{Total number of marbles}}. ] Without specific numbers, the exact probability cannot be computed.

To find the probability of picking a red marble, first determine the total number of marbles in the bag, which is 3 (green) + 2 (yellow) + 6 (blue) + 9 (red) = 20 marbles. The number of red marbles is 9. Therefore, the probability of picking a red marble is the number of red marbles divided by the total number of marbles, which is 9/20 or 0.45.
When a marble hits a row of marbles why does only one marble fly of?
When a marble hits a row of marbles, only one marble flies off due to the conservation of momentum. The kinetic energy from the first marble is transferred to the second marble at the end of the row, causing it to move while the others remain stationary. It's a chain reaction that propagates the energy through the row.
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
Is the probability that a blue marble will NOT be selected from a bag containing 9 red marbles 6 blue marbles 7 green marbles and 11 yellow marbles if one is selected randomly?
To find the probability that a blue marble will NOT be selected, first calculate the total number of marbles: 9 red + 6 blue + 7 green + 11 yellow = 33 marbles. The number of non-blue marbles is 9 red + 7 green + 11 yellow = 27 marbles. Therefore, the probability of NOT selecting a blue marble is 27/33, which simplifies to 9/11.
