Insurance is a means of protection from financial loss. It is a form of risk management, primarily used to hedge against the risk of a contingent or uncertain loss.
An entity which provides insurance is known as an insurer, an insurance company, an insurance carrier or an underwriter. A person or entity who buys insurance is known as an insured or as a policyholder. The insurance transaction involves the insured assuming a guaranteed and known - relatively small - loss in the form of payment to the insurer in exchange for the insurer's promise to compensate the insured in the event of a covered loss. The loss may or may not be financial, but it must be reducible to financial terms, and usually involves something in which the insured has an insurable interest established by ownership, possession, or pre-existing relationship.
The insured receives a contract, called the insurance policy, which details the conditions and circumstances under which the insurer will compensate the insured. The amount of money charged by the insurer to the policyholder for the coverage set forth in the insurance policy is called the premium. If the insured experiences a loss which is potentially covered by the insurance policy, the insured submits a claim to the insurer for processing by a claims adjuster. A mandatory out-of-pocket expense required by an insurance policy before an insurer will pay a claim is called a deductible (or if required by a health insurance policy, a copayment). The insurer may hedge its own risk by taking out reinsurance, whereby another insurance company agrees to carry some of the risks, especially if the primary insurer deems the risk too large for it to carry.
Umbrella insurance means that which is above "normal" policy limits. Ex., you get an extra $1M in coverage against liabilities.
It's surprisingly not that much more money - maybe $100-$200 more per year ($10-$20 extra/month) on top of a normal insurance policy. It would cover your home and...

Under an insurance policy, a maximum of of 5 claims may be filed per year by a policy holder. Let
p(n) be the probability that a policyholder files n claims during a given year, where n= 0,1,2,3,4,5. An actuary makes the following observations:
1) p (n) >= p (n+1) for 0<=n <=4
2) the...
If an insurer were to offer a policy against data loss from a catastrophic event such as an electromagnetic pulse, the insurer would be in no position to pay when the contingency occurs, the reason being that all of his own bank account will have been wiped clean by the same EMP. Therefore I...
