A real estate investor has the opportunity to purchase land
currently zoned residential. If the county board approves a request
to rezone the property as commercial within the next year, the
investor will be able to lease the land to a large discount firm
that wants to open a new store on the property. However, if the
zoning change is not approved, the investor will have to sell the
property at a loss. Profits (in thousands of dollars) are shown in
the following payoff table:
