LaserTech makes synthetic diamonds to be used in the manufacture of industrial lasers. For a recent sample of diamonds, they record the flaws of each diamond and, for the flaws, they create the histogram below. Diamonds with more than 14 flaws cannot be used in making lasers. In this sample, approximately what percent of diamonds can be used? Histogram of Flaws Note: Flaws are whole numbers and bins are "open on the right" with "width" of 10. This means the first bin goes from 0 4 (since flaws cannot be negative), the second goes from 5 to 14, the third from 15 to 24, etc
