# Insurance An insurance company needs to determine the annual premium required to break even on fire protection policies with a face value of $90,000. The random variable x is the claim size on these policies, and the analysis is restricted to the losses$30,000, $60,000, and$90,000. The probability distribution of x is as shown in the table. What premium should customers be charged for the company to break even? x 0 30,000 60,000 90,000 P(X) 0.995 0.0036 0.0011 0.0003

To determine

To calculate: The annual premium which should be charged from customers by the insurance company in order to break even on fire protection policies with a face value of $90,000 Explanation Given Information: The probability distribution of claim size of these policies:  Claim size (x)in$ 0 30,000 60,000 90,000 Probability 0.995 0.0036 0.0011 0.0003

Formula used:

If x is a discrete random variable which assumes values x1,x2,x3,......,xn with respective probabilities P1,P2,P3.......Pn then the expected value or mean X¯ is defined as E(X)=X¯=P1X1+P2X2+P3X3+.....+PnXn=i=1nP1X1

Calculation:

Consider the given probability distribution table can be represented as

 X 0 30,000 60,000 90,000 P(X) 0.995 0.0036 0.0011 0.0003

Where, X, P(X) represents claim and their respective probability, where for

X1=0X2=30000X3=60000X4=90000

And

P(x)=P1=0.995P(x)=P2=0.0036P(x)=P3=0.0011P(x)=P4=0.0003

Consider the formula for expected value E(X)=X¯=P1X1+P2X2+P3X3+
