Insurance is the practice of using contracts to reduce and redistribute risk. An insurance contract involves an insurer accepting a fixed payment, or premium, from the insured, and in return, committing to make payments if certain predefined events occur.

Historical Context

Insurance has been practiced since ancient times, with the earliest known instances dating back to ancient Babylonian and Chinese civilizations. The modern insurance industry began to take shape in the 17th century with the advent of maritime insurance in England and the establishment of Lloyd’s of London.

Expected Value

$$ E(X) = \sum_{i=1}^{n} x_i \cdot p_i $$

• \( E(X) \): Expected value of the insurance payout.
• \( x_i \): Possible payouts.
• \( p_i \): Probability of each payout.
