Answer: green cube=48% chance, blue=36% chance, white =16% chance.
Step-by-step explanation: 1. You want to add up all the cubes. There are 25 cubes in total (9+4+12=25)
2. For the green cube, we know there are 12 cubes, so there would be a 12/25 chance which is a 48% chance
3. The same thing applies to the blue cube. There are 9 of them so it would be a 9/25 chance (36%)
4. There are 4 white cubes. 4/25 is a 16% chance.
