Hello dear tutor, could you please help me to solve this problem please? Thank you very much in advance.

Suppose a proposed public policy could result in three possible outcomes:

1. present value of net benefit of $4,000,000
2. present value of net benefit of $1,000,000
3. present value of net benefit of -$10,000,000 ( a loss)

Suppose society is risk neutral and the probability of occurrence of each of these three outcomes are, respectively 0.85 , 0.10 and 0.05 should this policy be pursued or trashed? Why?
