Which Equation Represents the Way Complex, Multicomponent Decisions Would Be $\times$

Which equation represents the way complex, multicomponent decisions would be made according to utility theory?

A) Expected value = [(probability of outcome 1) $\times$ (utility of outcome 1) ] $\times$
[(probability of outcome 2) $\times$ (utility of outcome 2) ]
B) Expected value = [(probability of outcome 1) $\times$ (utility of outcome 1) ] +
[(probability of outcome 2) $\times$ (utility of outcome 2) ]
C) Expected value = [(probability of outcome 1) $\times$ (utility of outcome 1) ] -
[(probability of outcome 2) $\times$ (utility of outcome 2) ]
D) Expected value = [(probability of outcome 1) $\times$ (utility of outcome 1) ] ÷
[(probability of outcome 2) $\times$ (utility of outcome 2) ]
