In: Statistics and Probability
An automobile insurance company estimates the following loss probabilities for the next year on a $20,000 sports car:
Total Loss: .001
50% Loss: .01
20% Loss: .05
If the company charges $850 annual premium for this car, how much is the company's expected gain per policy?
X | P(X) | x. P(x) |

My professor wants the answer in the table above (if possible). I am unsure on how to answer this.
suppose X is loss without considering premium
X | P(X) | xP(X) |
20000 | 0.001 | 20 |
10000 | 0.01 | 100 |
4000 | 0.05 | 200 |
0 | 0.939 | 0 |
1 | 320 |
Expected value of X =
= 320
hence
Expected gain if premium = 850 is 850 - 320 = 530
