Suppose a life insurance company sells a $240,000 one year term life insurance policy to a 25-year old female for $210. The prob

Answer:

$112.08 every year.

Step-by-step explanation:

Let's suppose a game in which we bet a certain amount of money ''A'' to a certain result and the probability of that result is ''p''. If the prize that we get is ''P'' therefore the expected value of gain is :

$E=p(P-A)+(1-p)(-A)=pP-A$

Now,let's suppose that the female is ''betting on her death'' ⇒

P(she survives) = 0.999592

P(she doesn't survive) = 1 - 0.999592= $4.08(10^{-4})$

E(25-year old female) = $4.08(10^{-4}).(240000)-210=-112.08$

The negative sign of E is important.It means that every year the 25-year old female will lose $112.08.

Therefore, the expected value of this policy to the insurance company is $112.08 every year.
