Remember there is one less marble in the jar.
Marbles in a jar probability.
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.
A jar contains 24 marbles some are green and others are blue.
So the next time.
Have the children take turns answering the questions and placing the probability cards in front of each jar after each of the questions.
You can arrange the marbles however you like but each marble must be in a jar.
If we got a red marble before then the chance of a blue marble next is 2 in 4.
Finally multiply the probabilities and reduce to get 1 19.
Find the probability of picking green 4 20 then find the probability of picking blue 5 19.
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 4 black marbles and 3 red marbles.
13 is a prime number and 42.
If a marble is drawn at random from the jar the probability that it is green is 32.
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.
At least 1 red a jar contains 30 red marbles 12 yellow marbles 8 green marbles and 5 blue marbles.
For example if the answer is 2 3 the response should be 0 67.
So the probability of getting a blue marble is 13 42.
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.
Answer in decimal rounded off to 2 decimal places.
The total number of marbles in the second jar is 42 marbles and the total number of blue marbles in the jar is 13.
Place the possible card in front of the jar.
What is the maximum probability.
