A more thorough explanation:

A hazardous contract is a type of contract that is considered risky or uncertain for one or both parties involved. It is also known as an aleatory contract. This type of contract is based on an uncertain event or outcome, and the parties involved may not know the exact outcome or consequences of the contract.

• Insurance policies are a common example of hazardous contracts. The policyholder pays a premium to the insurance company, and in return, the insurance company agrees to pay out a certain amount of money if a specific event occurs, such as a car accident or a house fire. The outcome of the contract is uncertain, as the event may or may not happen.
• Another example of a hazardous contract is a gambling agreement. The parties involved agree to bet on a certain outcome, such as the winner of a sports game or the roll of a dice. The outcome is uncertain, and one party may win or lose money based on the result.

These examples illustrate how a hazardous contract is based on an uncertain event or outcome, and the parties involved may not know the exact consequences of the contract. This type of contract can be risky for one or both parties, as the outcome may not be in their favor.
