The probability of drawing a black marble from a bag is and the probability of drawing a white marble from the same bag is . What is the probability of drawing a white marble replacing it and then dra?
To find the probability of drawing a white marble, replacing it, and then drawing a black marble, you multiply the probabilities of each independent event. If the probability of drawing a white marble is ( P(W) ) and the probability of drawing a black marble is ( P(B) ), then the combined probability is ( P(W) \times P(B) ). This assumes that the events are independent due to the replacement of the marble after the first draw.
What is the probability drawing a blue marble from a bag of 18 marblesin a bag three of which are blue?
The probability of drawing a blue marble from a bag containing 18 marbles, of which 3 are blue, is calculated by dividing the number of blue marbles by the total number of marbles. Therefore, the probability is ( \frac{3}{18} ), which simplifies to ( \frac{1}{6} ). Thus, the probability of drawing a blue marble is approximately 0.167 or 16.7%.
What is the probability of drawing a black checker from a bag of 9 black checkers and 6 red checkers replacing it and drawing a red checker?

A bag has 13 green marbles What is the probability pf drawing out a green marble?
your probability would be 13/13. you would have a 100 percent chance of getting a green marble
What is the probability of drawing a red checker from a bag of 9 black checkers and 6 red checker's replacing it and drawing another red checker?
There are 9+6 = 15 checkers in the bag. 6 of them are red. 6 out of 15 are red. Drawing a red checker has a probability of P = 6/15 = 2/5 = 0.4 = 40% Since you replace the checker, the probability Q that red is drawn again remains 0.4. The probability of both events occurring (red drawn twice) equals the product of probabilities, PQ = (0.4)*(0.4) = 0.16.

What is the probability of drawing atleast one ball from a bag of 10balls?

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?

What is the probability of drawing a red checker from a bag of 9 black checkers and 6 red checker replacing it and drawing another red checker?
4 out of 25
There are 2 red marbles 3 yellow marbles and 5 blue marbles in a bag determine the probability of drawing a yellow marble from the bag?
3 in 10
A bag has 13 green marbles What is the probability pf drawing out a green marble?
your probability would be 13/13. you would have a 100 percent chance of getting a green marble
There are 2 red marbles 3 yellow marbles and 5 blue marbles in a bag determine the probability of drawing a red marble from the bag?
20% (or 2 in 10 chance)
Can the probability of an outcome be 1?
Yes, it certainly can if there is only one possible outcome. For instance, the probability of drawing a red ball from a bag containing nothing but red balls is equal to one.
If you have a bag containing 24 marbles If the probability of drawing a red marble is twice as likely not drawing a red marble how many red marbles are in the bag?
Suppose probability of drawing a red marble is p. Then p = 2*(1 - p) that is p = 2 - 2p or p = 2/3 So 2/3 of the 24 marbles are red 24*(2/3) = 16 red marbles.
What is the probability of drawing a red checker from a bag of 9 black checkers and 6 red checker's replacing it and drawing another red checker?
There are 9+6 = 15 checkers in the bag. 6 of them are red. 6 out of 15 are red. Drawing a red checker has a probability of P = 6/15 = 2/5 = 0.4 = 40% Since you replace the checker, the probability Q that red is drawn again remains 0.4. The probability of both events occurring (red drawn twice) equals the product of probabilities, PQ = (0.4)*(0.4) = 0.16.
