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%
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.
What is the probability of picking a blue marble from a bag of 4 red marbles 6 blue marbles and 1 white marble?
11 marbles total and 6 are blue so probability is 6/11
What is the probability of drawing 1 green then 1 blue marble from a bag with 5 blue marbles 5 red marbles 3 green marbles 2 white marbles?

A jar has 6 marbles 1 blue 1 white 1 green 1 yellow 1 red 1 black If 5 marbles are removed at random what is the probability that the green marble was removed?
5/6
If a bag contains 4 green marbles an 4 yellow marbles 5 white marbles what would be more likely to pull a red marble or a white marble from the bag?
You would be more likely to pull out a white marble as there are no red marbles in the bag.
What are the odds in favor of choosing a white marble from a bag containing 3 black marbles 4 green marbles and 6 white marbles?
The probability of drawing a white marble is .46
Explain how to find the probability of choosing a green marble from a bag of marbles containing 5 green 3 blue 6 red and 12 white?
If you pick only one marble from the bag, at random, it can be any one of 26 marbles. Out of these, 5 of the marbles are green. Thus, there are 26 possible outcomes out of which 5 are favourable - to the event that the marble is green. Therefore the probability of a green marble is 5/26. The calculations become more complicated if you consider choosing a green marble in several attempt: it depends on whether or not the marbles are replaced before the next one is picked.
A bag contains 4red marbles 2 white marbles a marble is selected kept out the bag and then another marble is selected what is the probability of selecting a red marble and then white marble?
2/6
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.
a bag contains 150 marbles some of the marbles are blue and the rest of the marbles are white in the bag there are 21 blue marbles for every 4 white marbles how many of each color marble blue and white are in the bag show or explain your thinking?

Suppose there are three white marbles and three black marbles in a bag and you want to remove two marbles What is the probability that you will select a white marble and then a black marble Express?
3/6 * 3/5 = 6/30 or 1/5 so you have a 20% chance of pulling a white and then black marble.
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 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%
If there are 3 black marbles 2 white marbles and 1 red marble what is the probability of selecting a black marble?
3/6 or 1/2 or 50%
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.
A bag contains 6 purple and 7 white marbles two marbles are drawn at random one marble is drawn and not replaced what is the probability that the fist marble is white and the second is purple?
