Answer:
pool the risks of healthcare costs.
Explanation:
In Insurance, risk tolerance refers to the willingness of an individual or organization to take a risk in business transactions in order to get a potentially positive reward.
Simply stated, risk tolerance in insurance is the willingness of an insured individual to increase his or her Self-Insured Retentions (SIRs) or deductibles by the insurer. For instance, the high risk associated with investments such as stocks, high-yield bonds, is often perceived by investors to be worth the higher reward such investment brings.
Generally, insurance companies across the globe charge millions of their customers (insured) premiums every year. This gives them the privilege of having a pool of cash which can be used to cover the cost of losses and destruction to the asset of a small fraction or percentage of its customers.
This simply means that, since insurance companies collect premium from all of their customers for losses which may or may not occur, so they can easily use this cash to compensate or indemnify for losses incurred by those having high risk.
Hence, the main function of insurance is to pool the risks of healthcare costs.
