Yes, and the value above 10 is 0. You are looking for (either formulation is correct), the range for the cheapest 90% of all claims, or the most expensive 10% of all claims, on a present value basis. Easiest is to find the most expensive 10%, which are claims between 2 and h. And then you want the value of of a claim at h, because that will be the cheapest among the top 10%, on a present value basis.
