A marble is selected from a random jar containing 3 red marbles 4 yellow marbles and 2 marbles what are the odds in favor of selecting a red marble?
The probability of selecting a red marble is 3/9
A bag contains 6 marbles Three red marbles two blue marbles and one white marble If two marbles are selected at random determine the probability that both are red?
one out of nine
A bag contains 3 red marbles 5 blue marbles 8 yellow marbles and 4 black marbles what is the theoretical probability of randomly picking each color marble?
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.
A bag contains 3 blue marbles 7 red marbles and 5 yellow marbles. If Joe picks 1 marble from the bag at random what is the probability that it will be blue?
A bag of marbles contains 13 marbles. 5 Blue, 3 Yellow, 4 Green and 1 Red. Leave all answers as a ratio in lowest terms. 18 points On a single draw, what is the probability of drawing a yellow marble? What is the probability of not drawing a yellow marble? What are the odds in favor of drawing a blue marble? What is the probability of drawing a red or yellow marble? What is the probability of drawing a purple marble? If you had to bet on drawing a marble of a certain color what color would you not choose?
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 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
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.

A box contains 8 green marbles 4 red marbles and 4 purple marbles if you draw a marble at random what is the probability that you will not draw a red marble?
Probability of drawing a red marble = 4/16 = 1/4 Probability of drawing not a red marble = 1 - 1/4 = 3/4
When a jar contains 5 white marbles 3 blue marbles and 2 green marbles and if one marble is drawn at random then what is the probability that it will be blue?
There is a probability of 3 that it will be blue.
What is the probablility of picking a green marble at random from a box that contains only 11 blue marbles?
The probability of picking a green marble from a box that only contains blue marbles is zero.
A bag contains 6 marbles Three red marbles two blue marbles and one white marble If two marbles are selected at random determine the probability that both are red?

A jar contains 22 yellow marbles 26 green marbles 17 red marbles and 20 purple marbles A marble is drawn at random what is the probability of not pulling out a purple marble?
probability of pulling out a purple marble = 20/85probability of NOT pulling out a purple marble = 1 - 20/85 = 65/85 = 13/17

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 8 red marbles 6 blue marbles and 9 green marbles If a marble is selected at random what is the probability of choosing a blue marble?
Number of different possible choices = 8 + 6 + 9 = 23Number of available successful choices (blue marbles) = 6Probability of success = 6/23 = 0.26087 = 26.087 %(rounded)
