Answer:
a) $430
b) -$90
Step-by-step explanation:
Given a random variable X with possible values
[tex]\large x_1,x_2,...x_n[/tex]
with respective probabilities of occurrence
[tex]\large P(x_1),P(x_2),...P(x_n)[/tex]
then the expected value E(X) of X is
[tex]\large x_1*P(x_1)+x_2*P(x_2)+...+x_n*P(x_n)[/tex]
a)
The expected collision payment would then be
0*0.85 + 500*0.04 + 1000*0.04 + 3000*0.03 + 5000*0.02 + 8000*0.01 + 10000*0.01 = $430
So the insurance premium that would enable the company to break even is $430
b)
The expected value of the collision policy for a policyholder is the expected payments from the company minus the cost of coverage:
$430 - $520 = -$90
Why does the policyholder purchase a collision policy with this expected value?
Because the policyholder does not know what the probability of having an accident is in her particular case.
Besides, it is better to have the policy and not need it than to need it and not have it.
The probability computed shows that the collision insurance premium that would enable the company to break even is $430.
How to calculate the probability?
The collision insurance premium that would enable the company to break even will be calculated thus:
= (0 × 0.85) + (500 × 0.04) + (1000 × 0.04) + (3000 × 0.03) + (5000 × 0.02) + (8000 × 0.01 + (10000 × 0.01)
= $430
The expected value of the collision policy for a policyholder will be:
= $430 - 520
= -$90
In conclusion, the policyholder purchase a collision policy with this expected because he doesn't know the probability of having an accident.
