$$4$ million over her construction cost, which excludes the land; and there is a $30$ percent chance that she can sell it to an insurance company for $$5$ million over her construction cost $($also excluding the land$).$ If$,$ instead of the shopping center, she decides to build the $1,500$ apartments, she places probabilities on the profits as follows: There is a $60$ percent chance that she can sell the apartments to a real estate investment corporation for #$3000$ each over her construction cost; there is a $40$ percent chance that she can get only $$2000$ each over her construction cost. $($Both exclude the land cost.$)$

If the land is not rezoned, she will comply with the existing zoning restrictions and simply build $600$ homes, on which she expects to make $$4000$ over the construction cost on each one $($excluding the cost of the land$).$
