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.
The outcome is that you have pulled a marble out of the bag.
The probability of rolling a number greater than 4 is 2/6, that is, 1/3. For the probability of pulling out a red marble, more data has to be known. Just put the number of red marbles in the numerator, the total number of marbles in the denominator. Finally, multiply the two probabilities.
If you reach into the bag, grasp, and withdraw your hand, the probability of pulling something out is about 100%.

2/6
Probability = number_of_white_marbles / total_number_of_marbles = 10 / (4 + 6 + 4 + 10) = 10 / 24 = 5/12 ~= 0.42
The probability of pulling a red or yellow marble out of a bag of 3 green 8 red 8 yellow and 3 black marbles is 16 out of 22, or about 0.73.
3/10 or 0.3 is the probability of picking a purple 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.
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 %
your probability would be 13/13. you would have a 100 percent chance of getting a green marble
