So the bag contains all the color marbles, which means you have to add all the marbles together.. 8+12+16= 36 there are 8 green marbles from all the marbles together, that forms a fraction of 8 / 36,that fraction can be simplified by dividing both 8 and 36 by 4 looking like 8/4 over 36/4 which will give you
2/9.!! That is the probability of a person reaching into the bad and randomly selecting a green marble.! Hope this helps!
