Using the information in the table, estimate how many hurricanes the
  Washington, D.C. area is likely to experience in an average decade? (See
  sidebar for hint.) What will be an ideal response?

 

Metropolitan area Area population (2004) Landfall probability () Risk ranking
  Boston 4,400,000 18 4
  Houston 5,200,000 24 3
  Miami 5,400,000 42 1
  New Orleans 1,300,000 36 2
  New York 18,700,000 18 4
  Washington, D.C. 5,100,000 12 5

Question 2

What is the range, from highest to lowest, of annual hurricane landfall
  probability experienced by the states along the Atlantic and Gulf Coasts?
  (Hint: You may want to turn off the Major Metropolitan Areas layer for a
  clearer view.) What will be an ideal response?
