Theories of subjective probobility ore viewed OS formol longuoges for onolyz-ing evi dence ond expressing degrees of belief. This article focuses on two probobility Iongouges, the Boyesion longuoge ond the longuoge of belief functions (Shofer, 1976). We describe and compare the semantics (i.e., the meoning of the scale) ond the syntax (i.e., the formol coIcuIus) of these Ion-guoges. We also investigote some of the designs for probobility judgment afforded by the two longuoges.
