What is the probability of getting a red marble?
If the marble is not “replaced”, the probability of the second drawing changes, since there are less marbles in the jar. The probability of drawing a red marble = 2/5.
What is the probability that the first marble is blue and the second is red?
Therefore, we can say that in answer to the question, the probability of the first marble is blue and the second marble is red is six over 49.
What is the probability of choosing a A black marble and then a white marble if the first marble is replaced?
Two marbles are chosen without replacement. The probability of selecting a black marble and then a white marble is 0.34, and the probability of selecting a black marble on the first draw is 0.47.
What is the probability that the marble is white?
What is P(white)? If a marble is selected at random, the probability it will be white is 50\%.
How do you find the probability of a marble?
If there are three red marbles and two blue marbles, then the probability of drawing any red marble is the number of outcomes in the event ” red,” which is equal to three, divided by the total number of outcomes, 5, or 3/5 = 0.6.
What is the probability of pulling a red marble first without replacing the red marble pulling a blue marble second?
The probability of the first marble being red is 943. After returning this marble to the bag, the probability of the second marble being blue is 1143. So the probability picking a red marble, and then a blue marble is 943⋅1143≈0.054.
What is the probability of getting a white marble from a jar which has 3 red 7 green and 10 white marbles?
Probability that murble is white P = 10/(3 + 7 + 10) = 10/20 = 1/2.
What is the probability that the marble will be any one color?
HENCE, the probability of getting any one colour is 1.
What are the odds of getting a red marble?
We can go one step further and see what happens when we pick a second marble: If a blue marble was selected first there is now a 1/4 chance of getting a blue marble and a 3/4 chance of getting a red marble. If a red marble was selected first there is now a 2/4 chance of getting a blue marble and a 2/4 chance of getting a red marble.
What is the probability of picking two pink marbles that are both pink?
The probability of picking 2 marbles that are both pink would be the product of the probability of choosing the first pink marble multiplied by the probability of choosing a second pink marble from the remaining marbles in the mix. This would be 1/2 * 4/9 = 2/9. To obtain the probability that is asked, simply compute 1 – (2/9) = 7/9.
How many marbles are in a bag of marbles?
A bag contains 3 white, 4 black, and 2 red marbles. Two marbles are drawn from the bag. If replacement is not allowed, what is the probability that the second marble drawn will be red? I disagree Stack Exchange Network
What is the probability of drawing a red on the first?
On the first, you have 10/16 chances to draw a red. Supposing this red is not replaced, the chance of drawing a second red will be 9/15; therefore, the probability of A is (10/16) * (9/15) = 0.375. Event B is translated into 2 events: Blue + (White or Red) or (White or Red) + Blue.
