It is the job of the insurance company to calculate Y and know how much to charge and if they cover it - this is what insurance companies do.
If Dan said they weren't covering it, that would be reasonable. It would also be reasonable if they said such events are more likely, so the policy costs more. But I was told some things would be covered, others would not be covered, and they couldn't immediately tell me which were which, and I will be better covered buying the policy now instead of waiting to get a straightforward answer.
