An urn contains 2 red and 2 green marbles. We pick a marble, record its color,...
Use a probability tree to answer the following. A jar contains 7 red marbles, 7 green marbles, and 7 blue marbles. What is the probability that you draw a red marble? = What is the probability that you choose exactly one of each color, if you pick 3 from the jar? = What is the probability that you draw 4 green marbles in a row if you do not replace the marbles after each draw? =
An urn contains three red marbles and five blue marbles. A marble is picked at random and is not replaced. A second marble is then picked from the urn. Determine the following: (a) P(both marbles are red) (b) P(both marbles are blue) (c)P(both marbles are the same color)
a) A urn contains one red marble, one green marble and one blue marble. An experiment consists of taking one marble from the urn, then returning it and drawing a second marble. What is the probability that exactly one red marble is selected? b) What is the probability that exactly one red marble is selected if the experiment is without replacement (marble is not returned)?
An urn contains 14 red marbles, 29 blue marbles, and 43 yellow marbles. One marble is to be chosen from the urn without looking. What is the probability of choosing a red marble?
3. Consider the following experiment. We have an urn with two marbles numbered 1 and 2 We pick a marble randomly, write down its number and return it to the urn. Then we add a marble with the mumber 3 to the um, choose one of the three marbles randomly, record its number and return it to them. We repeat this over and over: before thek + 1)st pick we add a marble with with the number k + 2...
An urn contains 15 different colored marbles, 7 are red, 5 are blue, and 3 are green. Part 1. If two balls are randomly picked from the urn without replacement a) b) Determine the sample space What is the probability of grabbing a red marble on the first pick and then a green marble on the second pick? Did you use the classical or empirical approach to calculate the probability in part b? Are these events independent or dependent? Disjoint...
An urn contains 27 red marbles, 25 blue marbles, and 43 yellow marbles. One marble is to be chosen from the urn without looking. What is the probability of choosing a red marble? Your answer should be to rounded to 4 decimal places.
QUESTION 9 A bag contains 1 green marbles and 3 red marbles. 6 times a marble is removed from the bag, its color noted, and then returned Success is getting a green marble. Find the probability of getting three green marbles. Round off to three decimal places.
An urn contains 21 red marbles, 19 blue marbles, and 40 yellow marbles. One marble is to be chosen from the urn without looking. What is the probability of choosing a red or a blue marble? Your answer should be rounded to 4 decimal places.
EXERCISE 16. Urn A contains 4 white and 3 red marbles, urn B contains 2 white and 5 red marbles. A marble is to be selected from urn A and another marble is to be selected from urn B. What is the probability that the two marbles selected are white? Answer. 8/49. Please show your workings. I have shown the possible answer already. Thank you!
