Please help me with questions 5, 6 and 7

5. expected loss = 600,000*0.01 + 100,000*0.02 + 30,000*0.03 = 8,900

discounted expected claim = 8900/1.08 = 8,240.74

6. Discounted claim = 8900*1.05^2 = 8,072.56

7. As the interest rates rises, the insurance premium decreases. Similarly as the claims tail increases, the premium decreases.
