![8. Consider the quantitative version of the risk formula
A. What quantity (dollar value) of risk is generated by a threat that will cause $5,000,000 in
damage if it occurs, and has a 0.1% chance of occurring in any given year?
B. Based on the quantitative risk calculated in part A, is it worth deploying a control that costs
$50,000 per year (easily possible if it requires hiring a dedicated employee)?
C. Consider the case that $5,000,000 in damages is likely to greatly exceed both the total
revenue and the emergency cash reserve of a small business (which typically recommended
to be in the ballpark of 6 months of operating expenses). How would you rate this threat for
such a company, qualitatively?
D. Based on the qualitative risk assessed in part C, is it worth deploying a control that costs
$50,000 per year? Why or why not?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff05ede74-ef08-4364-b9bf-c8386db5c820%2F6722e659-a550-40b9-bd4f-79cfcfa57c02%2Fapqqx5l_processed.jpeg&w=3840&q=75)
