The proportion of unsharpened colored pencils in Avery's sample is 2/50 = 1/25.
If this proportion holds for the entire basket of colored pencils, the expected number of unsharpened colored pencils in a basket of 300 would be 300 * (1/25) = 12.
Therefore, the answer is 12.
Avery randomly selects 50 colored pencils from a basket and finds that 2 are not sharpened. If the basket contains 300 colored pencils, how many would you expect to be unsharpened?(1 point)
