An auto insurance policy has a deductible of 4 with a maximum claim transmittal of 5. Auto loss amounts follow an exponential distribution of 8. Given the occurrence of an auto loss, calculate the expected claim gift made by this policy
Answers:
Say Y = total loss and X = loss to insurer

If Y <= 4, X = 0
If 4 => Y <= 9, X = Y - 4
If Y > 9, X = 5

Since exponential is a continuous distribution you need to integrate to find the probabilities.

E(X) = Int 0*F(Y) from 0 to 4 + Int (Y-4)*F(Y) from 4 to 9 + Int 5*F(Y) from 9 to infinity
