There Are 9 Red And 6 Green Marbles

You wish to know t probability that the single chosen green or blue marble.

There are 9 red and 6 green marbles.

So i could pick that green marble or that green marble. There are 35 marbles in a bag. 4 20 then find the probability of picking green again 3 19. Remember there is one less marble in the jar and that you assume the marble picked was green.

The measure of probability is number of favourable outcomes total possible outcomes a favourable outcome is a green marble of which there are 6. And then there s one blue marble in the bag. If we are too draw another green marble the same probability 6 15 will be resulted. There are a total of 14 green and blue marbles so the probability is 14 25 or 56.

These are clearly all yellow. Finally multiply the probabilities and reduce to get 3 95 share. The total number of marbles in the box is 25 that is 9 green 5 blue and 11 red. Solution from the condition we can determine how many marbles of each color were there in the jar.

What is the probability of that child getting a green marble. So i could pick that red marble or that red marble. There are 9 red and 6 green marbles in a bag. At this moment the bag becomes the same as it is before a green marble is drawn i e.

What percent of the marbles aren t blue. So this is all the possible outcomes. There are still 6 green marbles and 9 red ones. In the bag there are 6 green marbles and 12 red marbles.

There are 6 red 4 green 5 blue and 5 yellow marbles in a jar. 9 blue marbles 8 green marbles 4 red marbles 8 white marbles and 6 yellow marbles. Write the probability as a fraction in simplest form a decimal and a percent. There s one blue marble.

There s two green marbles in the bag. 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. In a jar of red green and blue marbles all but 6 are red marbles all but 8 are green and all but 4 are blue.

1 answer jim g. There are 9 red and 6 green marbles in a bag if a child reaches the bag randomly and picks 6. There s two red marbles in the bag. A child reaches in the bag and randomly takes one marble.

As both requirements have to be fulfilled the required probability is the multiplication of both 6 15 6 15.
