Final answer:
Project X, with an NPV of $3 million, should be chosen over Project Y, with an NPV of $2.5 million.
Step-by-step explanation:
Project X and Project Y are mutually exclusive investment options. Project X has a Net Present Value (NPV) of $3 million, while Project Y has an NPV of $2.5 million.
In this case, the project with the higher NPV should be chosen. Since Project X has a higher NPV of $3 million compared to Project Y's NPV of $2.5 million, Project X should be chosen.
Note that the risk associated with each project has already been considered in the NPV analysis. Therefore, based on the given information, Project X is the better choice.
