A bag contains 6 orange 7 green and 8 yellow marbles Find the probability of picking 3 yellow marbles if each marble is returned to the bag before the next marble is picked?
Well, honey, if you're reaching into that bag three times and each time you're pulling out a yellow marble and then putting it back in, the probability of picking a yellow marble each time is 8/21. Multiply that by itself three times because you're picking three marbles, and you get a probability of 512/9261. So, good luck with those yellow marbles, darlin'!
What is a probalitlity for math?
A probability is saying something like, "What is the probability of getting a red marble if there are 20 red marbles in a bag and fifty blue marbles?" The answer would be 20/70 or 2/7 because there are seventy marbles in the bag but you only want those twenty.
A bag has 13 green marbles What is the probability pf drawing out a green marble?

What is the independent and dependent event for pulling two marbles out of a bag?
The first marble is the independent event because its probability is only based on the sample space of the bag. The second marble is the dependent event because its probability is based on the sample space of the bag which has now been changed by the first marble.
Bill has a bag of marbles If he knows that his bag contains 2 blue 3 red and 4 clear marbles what are the odds for Bill choosing a clear marble or a blue marble if he pulls one marble from the bag?
2/3rd is the answer This is a case of probability, the probability of getting only blue marble is 2/9 and only clear marble is 4/9, since we are looking for either of blue or clear, we will add the probabilities and upon adding these two it is 6/9 which translates into 2/3rd.

Bag with 10 marbles: 3 orange, 5 black, 2 white.Rephrasing the question.If a marble is drawn from the bag, then returned to the bag, and a second marbleis drawn, what is the probability that the first marble turns out white and the secondmarble black ?The probability for a marble to come out white from the bag is:P(W) = 2/10 = 1/5The probability for a marble to come out black from the bag is:P(B) = 5/10 = 1/2The probability for a marble to come out white, put back in the bag and then take again a marble for a second time and turns out to be black is:P(B2|W1) = (1/5)∙(1/2) = 1/10 = 0.10 = 10 %
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
