There are 6 red 4 green 5 blue and 5 yellow marbles in a jar.
There are 9 red and 6 green marbles.
Indeed we have these equations where r is the number of red marbles g is the number.
Be careful letting children play with marbles they may swallow.
These are clearly all yellow.
Jun 21 2018 1 3 explanation.
At this moment the bag becomes the same as it is before a green marble is drawn i e.
Write the probability as a fraction in simplest form a decimal and a percent.
4 20 then find the probability of picking green again 3 19.
And then there s one blue marble in the bag.
There are 9 red and 6 green marbles in a bag.
What is the probability of that child getting a green marble.
Remember there is one less marble in the jar and that you assume the marble picked was green.
If we are too draw another green marble the same probability 6 15 will be resulted.
There are 9 red and 6 green marbles in a bag if a child reaches the bag randomly and picks 6.
As both requirements have to be fulfilled the required probability is the multiplication of both 6 15 6 15.

Solution from the condition we can determine how many marbles of each color were there in the jar.
9 blue marbles 8 green marbles 4 red marbles 8 white marbles and 6 yellow marbles.
So this is all the possible outcomes.
What percent of the marbles aren t blue.
There are a total of 14 green and blue marbles so the probability is 14 25 or 56.
There are still 6 green marbles and 9 red ones.
So i could pick that green marble or that green marble.
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.
In the bag there are 6 green marbles and 12 red marbles.
There are 35 marbles in a bag.
You wish to know t probability that the single chosen green or blue marble.
The total number of marbles in the box is 25 that is 9 green 5 blue and 11 red.
So i could pick that red marble or that red marble.
There s two green marbles in the bag.
There s two red marbles in the bag.
There s one blue marble.
A child reaches in the bag and randomly takes one marble.
The measure of probability is number of favourable outcomes total possible outcomes a favourable outcome is a green marble of which there are 6.
