Let X be the random variable representing whether the car is stolen or not, where X = 1 if the car is stolen and X = 0 if it is not stolen. Then, we have:
P(X = 1) = 0.75 (probability that the car is stolen)
P(X = 0) = 0.25 (probability that the car is not stolen)
Let Y be the random variable representing the insurance company's net profit. Then, we have:
Y = 1500X - P (where P is the premium charged)
The expected net profit is given by:
E(Y) = E(1500X - P)
= 1500E(X) - P
To find the premium that the insurance company should charge to have an expected net profit of $2000, we set E(Y) equal to 2000 and solve for P:
2000 = 1500(0.75) - P
P = 750
Therefore, the insurance company should charge a premium of $750 per year to have an expected net profit of $2000.
