Add all the stuff up:
7 + 4 + 5 + 6 = 11 + 11 = 22
probability of a green object or a cube, so add the green objects and the total cubes
11 green objects + 12 cubes. = 23
23 / 22

The only thing we're NOT counting are the BLUE spheres.

There are four of them, so 22 total objects - 4 blue spheres = 18 / 22 = 9 / 11
