There are no Bayesian calculations required in this problem. All required probabilities are given. $T$

You need to pick between tivo types of technology to develop and deploy on your electronic devices $($Tech A versus Tech B$).$ There is a congressional committee writing regulations that will effect the profitability of the two technologies. The regulations may come out to be favorable $(\mathrm{.}4)$ neutral $(\mathrm{.}4)$ or unfavorable. You must make your choice before the regulations are announced.

If you pick Tech A and the regulations are favorable the payoff is $$100M$ if neutral $$40M$ and if unfavorable $$-30M.$

If you pick Tech $B$ and the regulations are favorable or neutral the payoff is $$50M$ and if unfavorable $$30M.$

The technology with the best expected value is

Tech $A$
