Why is insurance cover necessary?

Insurance is simply the management of risk. By purchasing an insurance policy you are transferring risk to the insurance company for a price or premium paid. Insurance companies work like a coop in that they take the risk from many people and pool it together. The risk of one person dying for instance is hard to figure but the risk of a large number of people is much easier to figure. Using statistics, an insurance company can figure how many people out of a large group will die in any particular year. This way they are able to accept your risk of dying and contractually agree to a certain payment if you do die for a relatively smaller price. Life insurance is easier to compute that other types of insurance. Why? You will only die once and the company knows what they will pay. In auto insurance you can have more than one wreck and the payment required can vary greatly.
