There are 8 marbles that aren't black, out of a total of 12 marbles, so the probability is 8/12 or 2/3.
it would be red because the probability is 5/9
There would be a 7/19 or 36.84% chance of drawing a blue marble from the bag.
2/9
Probability of drawing a red marble = 4/16 = 1/4 Probability of drawing not a red marble = 1 - 1/4 = 3/4
There is a probability of 3 that it will be blue.
The theoretical probability of randomly picking each color marble is the number of color marbles you have for each color, divided by the total number of marbles. For example, the probability of selecting a red marble is 3/20.
it would be red because the probability is 5/9
There would be a 7/19 or 36.84% chance of drawing a blue marble from the bag.
The probability is 0.56
The theoretical probability of randomly drawing a green marble can be calculated by dividing the number of green marbles by the total number of marbles in the bag. In this case, there are 12 green marbles out of a total of 5 red marbles + 8 blue marbles + 12 green marbles, which is 25 marbles in total. Therefore, the theoretical probability of drawing a green marble is 12/25 or 48%.
2/9
Probability of drawing a red marble = 4/16 = 1/4 Probability of drawing not a red marble = 1 - 1/4 = 3/4
There is a probability of 3 that it will be blue.
The probability of picking a green marble from a box that only contains blue marbles is zero.
2/6
probability of pulling out a purple marble = 20/85probability of NOT pulling out a purple marble = 1 - 20/85 = 65/85 = 13/17
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.
