Yellow

Answer 1

I got 1/3 for red
I got 2/3 for yellow
and 1/3 for green but they was wrong, Since you only have three colors I put that on the bottom and went by equal numbers on top. Can someone explain this to me.

Answer 2

Hints:
Work out the following:

- equal numbers of red marbles and yellow marbles (call
x=number of red
x=number of yellow

- twice as many green marbles as red marbles
2x=number of green

Now work out the sample space and the corresponding probabilities.

Nora 4:
Hint for you.
If you provide attempted answers to the question, do add "(answer check)" to the end of "school subject", especially if you have a whole series of questions which makes it look it homework dumping.
