What is the risk exercise

You are working to minimize the transportation costs of shipping products from warehouses in New York, and Atlanta, to customers in the East, South, Midwest, and West regions of the US. A simulation was created to understand how the model changed if your estimate of shipping costs were slightly inaccurate. 100 runs of the simulation were completed, and the optimal value found. The histogram shows what was the optimal value most often. Use the image of the histogram of shipments to the Midwest region from Atlanta to answer the question.
