How to solve this Insurance Payment Variables question

Setup

Setup

Express the insurer payment as the loss above the deductible, floored at zero.

Y=(L500)+Y=(L-500)_+

Model

Model

Map each loss amount to its corresponding payment.

L:0,1000,5000,10000,15000L: 0,1000,5000,10000,15000
Y:0,500,4500,9500,14500Y: 0,500,4500,9500,14500

Compute

Compute

Weight the payments by their probabilities, then add the stated amount to determine the premium.

E[Y]=0.12(500)+0.08(4500)+0.04(9500)+0.01(14500)=945\operatorname{E}[Y]=0.12(500)+0.08(4500)+0.04(9500)+0.01(14500)=945
premium=945+75=1020\text{premium}=945+75=1020

Answer

Answer

The required premium is 1,020.

1020(C)\boxed{1020\quad\text{(C)}}
