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) | 
| D | ||
| D- | ||
| Sum | 
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
