To determine how many colored pencils would be unsharpened, you can use proportions. If Avery randomly selected 50 colored pencils and found that 2 were unsharpened, you can set up the following proportion:

2 unsharpened pencils / 50 total pencils = x unsharpened pencils / 300 total pencils

Cross-multiplying, you get:

50 * x = 2 * 300
50x = 600
x = 600 / 50
x = 12

Therefore, you would expect 12 colored pencils to be unsharpened out of 300 total colored pencils in the basket.
