You can insure a $27,000 diamond for its total value by paying a premium of D dollars. If the probability of loss in a given year is estimated to be 0.01, what premium should the insurance company charge if it wants the expected gain to equal $1,000?
x | D-27000 | D |
P | 0.01 | 0.99 |
E(X) = (D - 27000) * 0.01 + D*0.99
1000 = 0.01D - 270 + D*0.99
1000 + 270 = D
D = $1270.
Hence Insurance company should charge $1270 to expect a gain equal to $1000.
