Marbles in a jar probability.

A draw the tree diagram for the experiment. Have the children take turns answering the questions and placing the probability cards in front of each jar after each of the questions. Two marbles are drawn without replacement. 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.

So the next time. The chance is 2 in 5 but after taking one out the chances change. A jar contains 4 black marbles and 3 red marbles. Finally multiply the probabilities and reduce to get 1 19.

Place the possible card in front of the jar. At least 1 red a jar contains 30 red marbles 12 yellow marbles 8 green marbles and 5 blue 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. 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. If we got a red marble before then the chance of a blue marble next is 2 in 4. What is the maximum probability. Find the probability of picking green 4 20 then find the probability of picking blue 5 19.

A jar contains 24 marbles some are green and others are blue. You can arrange the marbles however you like but each marble must be in a jar. Remember there is one less marble in the jar. 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.

If a marble is drawn at random from the jar the probability that it is green is 32. So the probability of getting a blue marble is 13 42.
