Here's the Solution to this Question

Let Y denote the net gain to the company from the sale of a policy. There are two possibilities,

  1. The insured person dies before three years are over.
  2. The insured person lives the entire three year period

The probability in the second case is 0.9995 and in the first case, the probability is 1-0.9995=0.0005

The probability distribution of Y is

Y 2000 -998000

p(Y)  0.9995 0.0005

Therefore,

E(x)=\sum Yp(Y)=2000\times 0.9995+0.0005\times (-998000)=1999-499=1500

The expected value to the company of a single policy is 1500.
