The expected value of perfect information at D2 is larger than at D3.

Under Hurwicz and half optimism (α=0.5), D2 and D3 are equivalent.

The expected value of perfect information at D3 is larger than at D2.

According to Laplace, the expected profit amounts to 370 and D1 is either Y or N.

The company expects a profit of 200 when pessimistic, and D1 is either Y or N.

The modal profit is 450, which coincides with an optimistic strategy when D1 is N.
