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.
Marbles in a jar probability.
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.
What is the maximum probability.
A jar contains 4 black marbles and 3 red marbles.
You can arrange the marbles however you like but each marble must be in a jar.
If a marble is drawn at random from the jar the probability that it is green is 32.
A draw the tree diagram for the experiment.
Finally multiply the probabilities and reduce to get 1 19.
The total number of marbles in the second jar is 42 marbles and the total number of blue marbles in the jar is 13.
Remember there is one less marble in the jar.
Answer in decimal rounded off to 2 decimal places.
If we got a red marble before then the chance of a blue marble next is 2 in 4.
So the probability of getting a blue marble is 13 42.
Place the possible card in front of the jar.
Find the probability of picking green 4 20 then find the probability of picking blue 5 19.
So the next time.
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.
At least 1 red a jar contains 30 red marbles 12 yellow marbles 8 green marbles and 5 blue marbles.
Two marbles are drawn without replacement.
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.
A jar contains 24 marbles some are green and others are blue.
B find probabilities for p bb p br p rb p ww p at least one red p exactly one red.
