At this moment the bag becomes the same as it is before a green marble is drawn i e.
There are 9 red and 6 green marbles.
If we are too draw another green marble the same probability 6 15 will be resulted.
Indeed we have these equations where r is the number of red marbles g is the number.
And then there s one blue marble in the bag.
What is the probability of that child getting a green marble.
There are 9 red and 6 green marbles in a bag.
So i could pick that red marble or that red marble.
There are 6 red 4 green 5 blue and 5 yellow marbles in a jar.
So i could pick that green marble or that green marble.
There s two red marbles in the bag.
Be careful letting children play with marbles they may swallow.
Write the probability as a fraction in simplest form a decimal and a percent.
7 red 5 green 6 blue pick 7 6 1 14 marbles and at least 1 is red because 14 green blue 11 at least 1 is blue because 14 red green 12 at least 1 is green because 14 red blue 13 picking 13 marbles could result in green marble absence if all 13 marbl.
The measure of probability is number of favourable outcomes total possible outcomes a favourable outcome is a green marble of which there are 6.
There are still 6 green marbles and 9 red ones.
9 blue marbles 8 green marbles 4 red marbles 8 white marbles and 6 yellow marbles.
4 20 then find the probability of picking green again 3 19.
You wish to know t probability that the single chosen green or blue marble.
In the bag there are 6 green marbles and 12 red marbles.
Finally multiply the probabilities and reduce to get 3 95 share.
There are a total of 14 green and blue marbles so the probability is 14 25 or 56.
There s two green marbles in the bag.
As both requirements have to be fulfilled the required probability is the multiplication of both 6 15 6 15.
