You will add the distances and then you divide by the amount of distances you've added
example (21.3+22.1+22.2+20.9+23.6+22.8) that is 6 distances given then you would divide the total by 6
therefore your answer would be
22.15

Step-by-step explanation:
Hi Millie.
First we can realize that the number of cubes of each type does not matter, only the ratios between them. We see that if there are x yellow cubes, there are 3x blue cubes. And therefore, there are 5*3x green cubes, or 15x green cubes. This means that the cubes are in a 1:3:15 ratio, or that for every 1 yellow cube, there are 3 blue and 15 green cubes.
Now we can find the probability of picking a yellow cube. Since there are 18 non-yellow cubes for every yellow cube, this means that there is a 1/19 possibility of picking a yellow cube.
$23.58 divided by 12 = $1.965
Each roll is about $1.97 (if you round up)
