Suppose that you have purchased a 40-piece box of salt water taffy; taffy is a type of soft, chewy candy that became popular in the United States in the 1800s. The box is advertised as containing a random assortment of 8 flavors. Calculate the probability that at least one flavor is missing from the box.

If using an algebraic approach, explain your reasoning and any necessary assumptions. If using a simulation approach, be sure to clearly comment any code and describe your logic.
