Mr. Sam Golff desires to invest a portion of his assets in rental property. He has narrowed his choices down to two apartment complexes, Palmer Heights and Crenshaw Village. After conferring with the present owners, Mr. Golff has developed the following estimates of the cash flows for these properties:

Yearly Aftertax Cash Inflow (in thousands)	Probability		Yearly After Tax Cash Inflow (in thousands)	Probability
$70..................	.2		$75.....................	.2
75..................	.2		80.....................	.3
90..................	.2		90.....................	.4
105..................	.2		100.....................	.1
110..................	.2
