An actuary is a professional who uses their expertise in mathematics, statistics, and financial theory to assess and manage financial risks.

They are typically employed by insurance companies, financial institutions, and other organizations that face significant financial risks. Actuaries use a variety of mathematical models and analytical tools to help these organizations make informed decisions about managing their risks.

Some common tasks that actuaries perform include calculating the probability of future events, estimating the potential financial impact of those events, and developing strategies for minimizing or mitigating those risks.
