Two units of utility have been calculated to be $0\mathrm{.}45$ with low demand and reduced prices and $0\mathrm{.}65$ with high demand and regular prices. If we construct a large facility there is a $0\mathrm{.}35$ probability demand will be low and a $0\mathrm{.}65$ probability demand will be high. What is the utility of build large?
