The total number of marbles in the box is 25 that is 9 green 5 blue and 11 red.
There are 9 red and 6 green marbles in a bag if a child reaches the bag randomly and picks 6.

There are a total of 14 green and blue marbles so the probability is 14 25 or 56.
Remember there is one less marble in the jar and that you assume the marble picked was green.
Indeed we have these equations where r is the number of red marbles g is the number.
There s two green marbles in the bag.
Finally multiply the probabilities and reduce to get 3 95 share.
There are 9 red and 6 green marbles in a bag.
