Marbles In A Jar Probability

The total number of marbles in the second jar is 42 marbles and the total number of blue marbles in the jar is 13.

Marbles in a jar probability.

The chance is 2 in 5 but after taking one out the chances change. A jar contains 24 marbles some are green and others are blue. For example if the answer is 2 3 the response should be 0 67. So the next time.

A draw the tree diagram for the experiment. Remember there is one less marble in the jar. Have the children take turns answering the questions and placing the probability cards in front of each jar after each of the questions. Pose questions to the children about each of the jars and the probability of picking certain colored marbles.

B find probabilities for p bb p br p rb p ww p at least one red p exactly one red. 13 is a prime number and 42. You can arrange the marbles however you like but each marble must be in a jar. What is the probability that you pick 3 green no red 1 of each at least 1 blue marble if a jar contains 5 blue 3 green and 4 red marbles.

If we got a red marble before then the chance of a blue marble next is 2 in 4. If a marble is drawn at random from the jar the probability that it is green is 32. A jar contains 4 black marbles and 3 red marbles. Place the possible card in front of the jar.

Two marbles are drawn without replacement. Find the probability of picking green 4 20 then find the probability of picking blue 5 19. At least 1 red a jar contains 30 red marbles 12 yellow marbles 8 green marbles and 5 blue marbles. What is the maximum probability.

P getting a color other than red p 25 55 455 probability of this happening 3 times in a row is found by 455 455 455 094 example 2. Finally multiply the probabilities and reduce to get 1 19.
