Insurance works on this simple logic. Instead of each person having to face the demon of his or her loss alone, s/he contributes to a pool on the understanding that if misfortune does strike, the pool will be at hand to assist the person in getting back what has been lost. Since a large number of people contribute to the pool, there is enough money to compensate those who have suffered losses as well as to administer the fund and for the insurance company to take something home by way of profit. The larger the number contributing to the pool and the lower the number of losses, the lower the premiums. The converse also holds true.

It’s quite simple really. Elegant too. No voodoo involved. Just logic and common sense.
