Marbles In A Jar Probability

Remember there is one less marble in the jar.

Marbles in a jar probability. A jar contains 4 black marbles and 3 red marbles. What is the maximum probability. Find the probability of picking green 4 20 then find the probability of picking blue 5 19. Answer in decimal rounded off to 2 decimal places.

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. The total number of marbles in the second jar is 42 marbles and the total number of blue marbles in the jar is 13. At least 1 red a jar contains 30 red marbles 12 yellow marbles 8 green marbles and 5 blue marbles. Have the children take turns answering the questions and placing the probability cards in front of each jar after each of the questions.

So the probability of getting a blue marble is 13 42. 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. You can arrange the marbles however you like but each marble must be in a jar.

A jar contains 24 marbles some are green and others are blue. 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. Total number of marbles 23 4 27 marbles p green marble of green marbles of marbles total 4 27 0 148 so the probability is 4 27 which is about a 14 8 chance.

Two marbles are drawn without replacement. 13 is a prime number and 42. B find probabilities for p bb p br p rb p ww p at least one red p exactly one red. The chance is 2 in 5 but after taking one out the chances change.

Pose questions to the children about each of the jars and the probability of picking certain colored marbles. So the next time.
