The cumulative distribution function for health care costs experienced
by a policyholder is modeled by the function
F(x) = 1 - exp(-x/100) , x>0
The policy has a deductible of 20. An insurer reimburses the policyholder
for 100% of health care costs between 20 and 120 less the deductible.
Health care costs above 120 are reimbursed at 50%.
Let G be the cumulative distribution function of reimbursements
given that the reimbursement is positive.
Calculate G(115).
解答是 G(115)=F(130)
不過我115算出來的X是150
不知道是不是我哪裡算錯了
